Tuners

I frequently have the opportunity to acquire sets of vintage guitar and mandolin tuners. There are slot head tuners and solid head, 1920s- 1970s. All of the sets in this list are fully functional, any shortcomings of individual sets are described fully. The sets do not contain bushings unless specified. Contact me for pictures of sets that might interest you, but please be sure to reference the set number when emailing an inquiry..


Set #237:  1950s era Kluson DeLuxe 'single line' strip tuners with off-white buttons as found on Gibson J-45 and J-50 guitars of the period as well as on some LG series guitars.  The set is in excellent condition with only the slightest surface wear to the plating.  The off-white buttons have been replaced with modern reproduction buttons as the old set was crumbling.  The tuner button replacements are perfect repros by Blazer and Henkes. The turning ratio is 12:1 and all the tuners turn freely without tight spots or binding and all are tight with no slop in the gear fit or operation.  The set has its original mounting screws, the bushings are modern reproductions of the originals.
Set 263:   Mid to late 1960s Grover rotomatic "Pat. Pend" marked tuners as were found on the D-28 and D-35 of the late 60s. This set has rather uniform pitting in the plating on every tuner but they are functionally fine.  Would look right on a late 60s D-28 or D-35 that has a little wear. Original mounting screws. 
Set 311:  Early 20th century brass plate strip tuners with hash mark decoration, probably teens, reverse gear, slightly unusual post spacing measuring 1 3/8” from the D to A string, and 1 13/32” from the D to E string and the same corresponding measurements on the treble plate.  Might fit a guitar with holes drilled at an even 1 3/8” with a little coaxing.  These are for slot head and are very similar to the brass plate Waverlys found on most Martin style 18 slot head guitars during the 20s.  Functionally and cosmetically very good. 
Set 317:  Late 1940s Kluson deluxe strip tuners as found on Gibson J-45 and J-50 guitars, the LG series and others.  This set is the “no line” variety, meaning that they have no Kluson marking on the gear cover, neither do these have any patent marking. The no-line variety of this tuner was in use from about 1948 to (I think) about ’51 or ’52.  The barrels are brass and ¼” diameter.  The off-white buttons are replacements.  The plating shows minor pitting and very light corrosion but it is superficial and the tuners function well.  I don’t know if I’ve got a set of bushings for these, I will check on request. 
Set 332:  Gold Grover Rotomatics, probably 1970s or 80s.  Found on some Gibson and Guild guitars.  They are a little dirty but will clean up easily if desired, the plating on the buttons and housing is worn but the look is right for an old guitar.  Replaced mounting screws. 
Set 338:  Super rare and gorgeous brass plate, floral engraved slot head tuners from the late 19th or early 20th century, most likely made by Waverly.  I’ve seen these exact tuners on several Martin 0-28 and 0-21 style guitars from the 1890s through about 1910.  The post spacing is 1 3/8”.  Functionally good, all original parts including the buttons, which are in good shape. 
Set 383: : Late 1940s Kluson deluxe strip tuners as found on Gibson J-45 and J-50 guitars, the LG series and others. This set is the “no line” variety, meaning that they have no Kluson marking on the gear cover, neither do these have any patent marking. The no-line variety of this tuner was in use from about 1948 to (I think) about ’51 or ’52. The barrels are brass and ¼” diameter. The off-white buttons are replacements. The plating is in good shape and the tuners function well. I don’t know if I’ve got a set of bushings for these, I will check on request.
Set 386: 1960s Kluson Deluxe double line strip tuners as found on many Gibson guitars of the era as well as other quality makes. This set has the original buttons in good condition, and the plating is clean. All of the tuners turn freely and hold. Mounting screws and bushings are modern replacements
Set 391: Super rare Grover strip tuners with ‘open book’ plate ends (same shape as a Gibson headstock) in nickel plating with off-white buttons. The set is in excellent cosmetic condition and very good functional shape, though one worm gear and button shaft has been replaced with a brass worm gear and shaft from another set of Grover tuners. Mounting screws are replacements. These were found on some Gibson and Larson Brothers guitars (I’ve seen this nickel version on more Larsons than Gibsons).
Set 396: 1950s/60s Waverly strip tuners for solid headstock as found on many Harmony and Gretsch guitars, as well as other makes. This set has black buttons, all of the parts are original and the set is in good functional order. Don’t know if I have bushings for these, please inquire if interested.
Set 400: 1930s Grover open gear individual tuners as found on some Martin flat tops and also on some brands of archtop. This set is in very good condition cosmetically and functionally, the plating is in good shape and none of the shafts are bent. All of the parts are original including mounting screws and bushings. The set has a 12:1 ratio and the shafts are 7/32”. Rare set.
Set 412: 1930s Waverly nickel plate strip tuners with saw-tooth plate end and fleur-de-lis plate engraving. The set is for solid head mount but if you need them for slot head just let me know as I may have barrels to convert for slot head. This set was found on many National resonator guitars and Maybell guitars (as solid head tuners) as well as on some early 30s Martin slot head guitars. The set is in excellent cosmetic and functional condition. The buttons are replaced with correct reproductions. No bent shafts or other damage. The turning ratio is 12:1, barrels are 7/32” in diameter. The set has the original mounting screws and bushings. Rare.
Set 417: Super rare 19th century set of slot head tuners that were removed from a circa 1860 Martin 2-17. The set looks like brass in the pics but it is actually silver plated. The set is good functionally and has the original mounting screws. The post spacing is 2 5/16". The bone buttons show cracks and a couple appear to have been glued but they are solid to the shafts and will work fine.
Set 433: 1930s Kluson open gear strip tuners as were found on most pre-war Gibson guitars and other makes as well. The set has had the buttons replaced with perfect repros, all other parts original. Functionally and cosmetically good. Barrels measure 1/4" in diameter, 12:1 ratio. Mounting screws are replacements, no bushings currently but a set might turn up, inquire.
Set 438: 1930s Waverly strip tuners for solid headstock in nickel finish with ornate 'flowers and fronds' decoration. These tuners have the 'saw tooth' plate end shape. The buttons are ivoroid. All parts are original. This set has barrels for solid headstock but if you need this set for slot head let me know, as I may have slot head barrels I can swap out. The plating is super clean, no corrosion or pitting and the buttons are solid. Turning ratio is 12:1 and the barrels are 7/32” in diameter. In solid head configuration these were found on some Gibson Style 0 'Artist' guitars and Gibson Harp Guitars. In slot head configuration these were found on some 12 fret Martin style 42 and 45 guitars. Very rare set.
Set 439: 1930s Waverly strip tuners for solid headstock with ornate plate decoration and off-white buttons. This set has barrels for solid head mount, but I've also got period slot head barrels to convert this set if required. The plating is excellent, bright and clean. All parts are original and in good working order, no bent shafts or other issues. 12:1 ratio, 7/32” barrels. This set was found on some presentation grade Washburn guitars and I believe also on some high end Larsons. Very rare set.
Set 444: 1930s/40s Waverly WG-31 strip tuners in nickel for solid headstock guitar. These were found on some Gibson L series guitars as well as some Vega flat top and arch top instrument, some Larsons and Weymanns and other quality makes. They were found on Martins also but generally the slot head variety, I may have slot head barrels available to convert these so ask if you need them for slot head. This set has some corrosion to the plating but functionally they are good and the buttons are in excellent shape. There are no bushings or mounting screws, you'll have to come up with those separately. All the tuners turn smoothly, no bent shafts. 12:1 ration, 7/32” barrels, 1 3/8” barrel spacing.
Set 458: 1950s Kluson mandolin tuners...this set was removed from a 50s A style Gibson mandolin. The tuner plates show a little corrosion but would likely clean up well. They are functionally good. The buttons have shrunken, they can be replaced by the purchaser or I can do that as a part of the purchase price. Original bushings are included, if you'll need mounting screws please let me know and I'll check for availability.
Set 465: 1930s Kluson strip tuners as were found on just about every Gibson guitar during the pre-war era (L-00,L-0, J-35, etc). The set has some very light corrosion on one plate but this may clean up with a little effort. The buttons are perfect replacements of the originals (from Antique Acoustics). The barrels have a 7/32" diameter and the turning ratio is 12:1. The set has the Kluson trade mark and patent stamp on the show-face of each plate surrounding the inner most mounting screw holes. Nice old set. Mounting screws and bushings available if needed.
Set 474: 1950s Waverly individual tuners with plastic buttons for solid headstock. These tuners were found on many style 0 and 00-17 Martins during the 50s and even on some style 18 guitars of the same sizes. Also found on most Gretsch acoustic and many electric guitars of the 50s/60s. The set is complete, all original parts. Though not pictured I do have the original hex bushings and will supply mounting screws (replacements). The barrels are 7/32”, 12:1 ratio. The set functions smoothly and is in good cosmetic condition.
Set 505: Super clean 1930s Kluson strip tuners with off-white buttons for solid head mount, this set is the higher grade of Kluson strip tuner that has the incised line of decoration around the perimeter, it also has the Kluson trade mark and patent stamp around the inner two mounting screw holes on the show-face of the plate.

Set 507: 1930s Kluson strip tuners for solid headstock with off white buttons. These were found on many Gibson models in the 30s including the L-0 and L-00, J-35, as well as some others and quality guitars from other manufacturers as well. This set bears the patent stamp and Kluson manuacturing marks on the outside face around the inner mounting screw holes. The plating is in excellent shape, the buttons may be replacements (not sure). 12:1 ratio, 7/32” barrels. All turn freely/easily. I don't have bushings or mounting screws with this set at the time of listing, if you'll need them mention them with your inquiry and I'll check on availability.

The set has replacement buttons from Antique Acoustics (perfect repros of the originals). The plating on this set has a fair amount of pitting/corrosion though they have been cleaned, so they would look most at home on a worn guitar. 12:1 ratio, 1/4” barrel diameter. All turn freely and hold well. No bushings or mounting screws.
Set 517: 1950s Waverly open gear individual tuners with metal buttons.

This set is in excellent shape, plating intact and clean, original bushings and mounting screws. All turn freely and hold well.

Set 529: War time Kluson strip tuners for solid headstock and black buttons as were found on some Gibson guitars of the war years and many Kalamazoo guitars.

Set 536: 1950s Kluson Deluxe strip tuners ('no line'), this set has had the buttons replaced with repros from Antique Acoustics. The plating on the tuners is in good condition and the tuners turn freely and hold well. These tuners were used on many Gibson acoustics in the 50s and many other quality guitars as well. 12:1 ratio. Original mounting screws included, no bushings, as if you need them as I may have set I can supply with the tuners.
Set 537: 1950s Waverly individual tuners with metal buttons. These were found on Martin style 18 small body guitars during the 50s. Also found on a lot of Gretsch guitars in the same era. The set is in good cosmetic order with no corrosion or lost plating and all the tuners work well. Two shafts were bent when I received the set but they have been straightened, one button has a few scratches on it from what looks like the jaws of a tool of some kind, but this is minor and visible only on close inspection. This set has all of its original parts including bushings and mounting screws, in good working order. 7/32” barrels, 12:1 ratio.

Set 538: Late 1960s Grover “Pat. Pend” Rotomatic tuners as were found on the D-18 (starting in '65) and D-28 (starting in '59). The set is in excellent condition with all original parts, the plating is intact and clean.  It is made up from two different sets however, though they are a turning match.  There's a little dirt and crud on a few of the tuners but the plating is all clean, so if the buyer wanted them to be bright and shiny all that would be needed is a light cleaning.  Functionally good.
Set 539: 1960s/70s Waverly strip tuners for solid headstock, these tuners were found on many Harmony guitars of the period, both electric and acoustic. This is the plainest version of this tuner. All the parts are original and clean, no bent shafts or other issues. The turning ratio is 12:1 and the barrel diameter is 7/32”. No mounting screws or bushings with this set.

I don't currently have bushings matched up with these, if you'll need bushings please inquire at time of purchase and if I've got them I'll toss 'em in.
Set 547: 1930s Kluson strip tuners for solid head stock as were found on many Gibson flat top guitars of that era. This set has the Kluson patent mark and manufacturing stamp on the outside face of the plate, around the center pair of mounting screw holes. The plates are steel and the barrels, shafts and gears are brass. The off-white buttons are replaced but perfect repros of the original Kluson buttons. The tuners show some age to the surface and light pitting but no serious corrosion or rust. All of the tuners turn freely and hold well. 12:1 ratio, 7/32” barrels. I do not currently have bushings paired with these, if you'll need bushings with the set please inquire about availability.
Set 552: 1930s Kluson strip tuners for solid headstock as were found on most Gibson guitars of the pre-war era (L-0, L-00, some J-35s, archtops and Kalamazoos). This set has the patent stamp and manufacturer's marking on the underside of the plate. The barrels, gears and cap screws are original, the off-white buttons are perfect reproductions of the original Kluson buttons. Cosmetically good, the plates show slight age related surface discoloration and the slightest pitting but no rust or significant degradation. Functionally good, the tuners turn freely and hold well. 12:1, 7/32” ratio. I do not have either bushings or mounting screws with the set at the time of listing, if you will require either please inquire and I'll see what I've got available.
Set 553: early 70s Grover Rotomatic tuners such as were found on the Martin D-28 and D-18 through the 70s. This set is in good cosmetic and functional order with no plating loss, original washers and mounting screws.
Set 556: 1930s Kluson open gear strip tuners for solid head, these were found on many Gibson guitars of the era as well as some other quality brands. This set has the Kluson trade mark and patent stamp on the show face of the plate around the inner two mounting screw holes. The buttons are replaced on this set (perfect repros of the originals from Antique Acoustics) as well as a few of the cap screws. The plating is in good condition and the tuners function well. Period bushings and mounting screws. 7/32 barrels and 12/1 ratio.
Set 563: early 70s Grover Rotomatic tuners that were found on all Martin D-18, D-28 and D-35 guitars through the 70s. The set is chrome plated with all original parts including the mounting screws. Functionally and cosmetically excellent.

Set 565: 1950s Kluson K-500 “waffle back” tuners as were found on the Martin D-28 in the early to mid-1950s. This set has all of its original parts including bushings and mounting screws. The plating shows some wear and light surface discoloration/tarnish but the tuners function well and hold. No bent shafts. They have just the right look for a guitar that shows proper wear for its age. 1/4” barrels and 12:1 ratio.

Set 575a: RARE late 40s/early 50s Kluson metal button individual tuners, these were found on the Martin D-18 and 000-18 from 1947 through the early 50s. These are hard to find with the buttons intact, and the buttons on this set are perfect. The overall condition of this entire set is excellent, no rust or pitting of the plating, no cracks or degradation of the buttons, no bent shafts or other problems. Original bushings, mounting screws replaced but correct type. Functionally excellent. 12:1 ratio, 1/4” barrel diameter.

Set #578: 1960s Grover “pat. Pend' Rotomatic tuners in gold finish. These tuners were found on the Martin D-42 and D-45 in '68/69, but were also used on the Gibson Les Paul Custom and SG Custom in the early 60s, the Gibson J-200 from '58-'61 and the Gibson Barney Kessel in the mid '60s. This set works fine but the plating is well worn. All the bushings, washers and mounting screws are present and original.
Set 589: 1930s/40s Waverly WG-31 nickel plate tuners, this set has barrels for solid head mount meaning that they could have come from a Gibson Nick Lucas, Style 0 Artist, L-1 or L-2. But with slot head barrels these were also used on Martin slot head guitars of the era like the 0-21 and 00-21. If you need this set for slot head guitar let me know, as I may have barrels available to convert the set for slot head use. The set is in very good cosmetic and working order no significant plating corrosion and no plating loss. Buttons, gears, barrels and bushings are original, as are the mounting screws as far as I can tell. Very rare set.
Set 593: War time set of Kluson strip gears as were found on many Gibson guitars of the period. This set is in good working order though the plates look like they were cleaned with a wire brush or heavy steel wool as it is clear that the surface has been abraded. There is no corrosion but the plating is gone. The buttons are perfect repros of the original Kluson buttons by Antique Acoustics. 1/4” barrels. In many cases these tuners were mounted with no bushings at all, so I have no paired bushings with the set (or mounting screws). If you will need mounting screws and/or bushings for this set make sure to mention that when inquiring and I will see what I've got on hand.
Set 599: 1930s Kluson open gear strip tuners as were found on many Gibson models of the pre-war era. This set has the buttons replaced by perfect repros of the originals but the rest of the parts are original. The plating is in very good condition, the plates bear the manufacturing and patent stamp around the mounting screw holes on the show face of the tuners. Functionally excellent. If you'll need bushings and mounting screws with the set let me know when you inquire and I'll check to see what I've got available.
Set 602: 1930s/early 40s Kluson strip tuners with original off-white buttons as were found on the Gibson J-35, some L-1 and L-2 model guitars, some lap steels and other quality brands. This is the fanciest grade of this style Kluson tuner in that it bears a single line of incised decoration around the perimeter of the plate. The plating is in excellent condition though one plate has a little corrosion and plating loss at either end. There are no bent shafts and all the tuners turn smoothly and hold well. All of the parts are original including the amber buttons. The set has barrels of 7/32” diameter and a 12/1 ratio. Period and style correct bushings (not pictured) are included, the mounting screws are replacements but are period.
Set 603: 1930s Waverly WG-31 strip tuners with “Oak Leaf” engraving for solid headstock. These were found on some Gibson model guitars (L-2, Nick Lucas, Style 0, Harp Guitar), but with slot head barrels these were the tuners used on most style 28 and higher end Martin slot head guitars from the late 20s-30s. If you need this set for slot head mount let me know as I may have barrels available to convert them to slot head. The set is in excellent condition overall with all original parts, no bent shafts and good functionality. The plating is in excellent shape though it is under some dirt so it looks a little dull, would clean up well and look brand-new bright with a good cleaning if desired. The set bears the Waverly Musical Instrument Products Co. stamp on the underside of the plate. 7/32” barrels, 12:1 ratio. If you are buying these for solid head mount and will need bushings let me know and I'll see what I've got. Very rare set.
Set 609: Super clean set of 1930s Kluson strip tuners with the manufacturer's mark and patent mark around the mounting screw holes on the show face of the plates. These were found on many pre-war Gibson flat top and arch top guitars. The tuners have no corrosion, no bent shafts or other cosmetic or functional problems. The buttons are modern replacements from Antique Acoustics. The barrels have a 7/32" diameter, 12:1 ratio. As of this writing I do not have bushings or mounting screws paired with this set but if you'll need them let me know at the time of your inquiry and I'll see what I have available.
Set 614:  Late 40s/early 50s Kluson metal button individual tuners as were found on most style 18 Martin guitars during that era.  This set is in excellent condition cosmetically and functionally, original mounting screws included.  I do not have the bushings, let me know if you'll need them when you inquire and I'll see what I've got available.  1/4" barrels, 12:1 ratio.
Set 617: 1950s/60s Waverly strip tuners for solid headstock guitar as were found on many Harmony and Gretsch guitars, some Guilds as well in that era. The set is in excellent condition with all original parts and spotless plating, no bent shafts. No mounting screws or bushings, inquire if you'll need them as to availability.
Set 618:  1960s Waverly WG-31 tuner for slot head guitar as were found on Martin 0-16 NY, 00-21 NY and 00-21 guitars in the 60s and early 70s.  Also found on the 00-21 going back to the 1950s.  This set is made from a treble and bass plate from two different sets, they are a turning match, but I think from slightly different eras as the buttons are very slightly different from each other.  The buttons are original on each plate, but a little thinner on one plate than the other.  One plate has a little more wear than the other as well.  Functionally good.  No mounting screws.
Set 622:  circa 1910 Dinsmore & Jager strip tuners as were found on many style 28 Martin slot head guitars in the early 20th century.  These tuners appeared on Martins between the Seidels that Martin used in the 19th century, and the Waverlys they would begin using by the 20s.  This exquisite set is brass, possibly gold plated, though it is hard to tell for sure.  The plate end has a 'saw tooth' shape and the plates are beautifully decorated with a floral motif.  The buttons are solid bone.  Mounting screws included, barrels measure 1/4".  The tuners are in excellent functional and cosmetic condition.  Super rare.
Set 623:  Wartime Kluson strip tuners with modern replacement buttons from Antique Acoustics.  These were found on many Gibson flat tops of the WWII era. The set is very clean cosmetically, functionally good.  Barrels measure 1/4" in diameter.  No mounting screws, let me know if you'll need them and I'll check to see what I've got available.
Set 624: 1950s Waverly open gear individual tuners with plastic buttons, these were found on most Martin style 15 and 17 guitars during the 50s and early 60s as well as many Gretsch guitars during the same era. Harmony also used these tuners extensively. All original set including rolled bushings and mounting screws. The rolled bushings indicate that this set likely came off of a Harmony, hex bushings available if that's what you need for your guitar (Martin or Gretsch used hex bushings)
Set 629: 1930s set of nickel plate Waverly WG-31 slot head tuners as were found on Martin style 21 and some style 28 guitars as well as other quality slot head brands such as Weymann, Vega, Larson and others. With solid head mount barrels these tuners were found on some Gibson L-1 and L-2 guitars, some Nick Lucas and Style 0 Artist model instruments among others. This set is in excellent condition with all original parts, no bent shafts, super clean and functionally perfect. Very hard to find, and as clean as you are likely to see.
Set 633: 19th century nickel silver plated, solid pearl button strip tuners with an elaborate stamped decorative pattern along the plate. These tuners are exquisite in every detail, certainly would have been found on only high end instruments of the 19th century. While the vast majority of Martin instruments from the 19th century used either Jerome (pre-1860s) or Seidel (mid-1860s and later), Robert Corwin's vintagemartin.com website shows an 1874 Martin 1-28 with these tuners and they show all indication of being original to the guitar. While they were not widely used on Martins, it is apparent they were used on some. The barrel spacing is 1 11/32”, the barrels measure 7/32” in diameter. If you have a 19th century Martin with a hole spacing of 1 11/32” in the headstock this is likely the right set for your guitar. The set is in excellent functional and cosmetic condition. Stupid rare. DP1 
Set 636: Fine set of teens/20s nickel plate strip tuners for slot head guitar with solid pearl buttons and 'hash mark' decoration on the plates. Don't know who made these for sure, the gears have a shape and cut that looks much like early Dinsmore & Jager tuners, could be Waverly as well but I can't say with any certainty. The plating and buttons are in excellent condition and the tuners function well. The plates are 4 3/16” in length and the barrel spacing is 1 3/8”. They are early enough to be 'reverse gear' orientation. Not 100% certain what they went on either, but a colleague who is well versed in Larson Brothers guitars suggested that these were found on some high end slot head Larsons. DP4.
Set 637: 1930s Beautiful set of gold plated strip tuners for slot head with fancy decoration pattern and solid pearl buttons that were found on high end pearl trim Weymann guitars and some presentation grade pearly Washburn guitars as well. Though not marked these are most certainly made by Waverly. The barrel spacing is 1 3/8” and the barrels are 7/32” diameter. The tuners are in very good working condition and good cosmetic condition. The plating is clean and bright. One of the pearl buttons has a tiny chip at the base but all 6 are very solid. 3 of the 6 button shafts have a very slight bend/wobble, but it is very slight and not enough to impact function nor enough to have much of an impact on the feel when turning. Very rare set. DP6.
Set 638: Holy cow...so clean and classy...this set of 1930s Waverly slot head tuners boasts gold plating, “flowers & fronds” decorative pattern, and solid pearl buttons. Tuners don't get fancier than this. The set is in exceptional condition cosmetically and functions great. No bent shafts or other problems of any kind. 1 3/8” barrel spacing and 7/32” diameter. Appropriate for the best dressed of the best dressed...while most Martin style 45 slot head guitars had nickel tuners with engraving some had gold engraved/pearl buttoned tuners such as these. You are not likely to see another set. DP7
Set 639: 1920s Waverly nickel plated strip tuner for slot head (bass side only...this is NOT a complete set) with solid pearl button and 'flowers & fronds' decorative pattern. Found on some style 42 and 45 Martin slot head guitars of the 20s as well as some pearl Larson brothers guitars. The plate is in exceptionally fine condition, no bent shafts and spotless plating, 1 3/8” spacing and 7/32” barrels. DP8
Set 641: Very clean set of teens/20s Waverly nickel plate/pearl button strip tuners for slot head with hash mark decoration. This same set of tuners with ivoroid buttons were used on Martin style 28 slot head guitars in the teens/20s but I've not seen these with pearl buttons on a Martin. A colleague with significant knowledge of Larson instruments suggests that these were used on pearly Larsons during that period. Excellent condition cosmetically and functionally. DP11
Set 643: Super clean 1930s set of Kluson strip tuners with black plastic buttons, these were commonly found on Gibson made Kalamazoo KG-11 and KG-14 models as well as many archtops made by Gibson. The set is as clean as I've seen, no degradation to the plating and the original buttons are in excellent shape. The barrels are 7/32” in diameter and the turning ratio 12/1. I do not have bushings or mounting screws for this set at the time of listing, if you'll need them please inquire as to availability.
Set 648: 1950s/60s Kluson tuners for banjo as were found on the Gibson RB-250. These tuners are nickel plated and in excellent condition cosmetically and functionally, and the set of 4 (no 5th string tuner available) comes with original bushings and mounting screws. Stair-step housing, keystone buttons.
Set 649: set of 4 1920s/30s Grover geared (4:1 ratio) tenor banjo or tenor guitar tuners with ivoroid buttons. The set has all original parts and is in excellent cosmetic and functional condition, the plating and buttons are clean.
Set 650: Full set of 20s/30s Grover two-tab banjo tuners for 5 string (5th string peg included) with original hex bushings and mounting screws. The plating is in excellent condition as are the ivoroid buttons. The housings are securely attached to the base plates (these two elements coming apart is the most common problem with this style tuner), fully and smoothly functional (4:1 ratio).
Set 656: 70s/80s Schaller chrome plated 3 on a side tuners as were used on many quality acoustic guitar brands. The tuners have the Schaller “S” logo and “made in Germany” on the back of the housing. The buttons are somewhat on the large side compared to other Schallers I've seen. Washers and mounting screws included.

Set 660: RARE late 1920s Waverly strip tuners in nickel with “flowers & fronds” decorative pattern and ivoroid buttons. The set has barrels for solid headstock but I have barrels to convert the set to slot head use if you need them for a slot head guitar. Some high end Gibsons of this era used these tuners (solid head) and with slot head barrels they were found on many Martin guitars of the era in styles 28 through 42. Functionally and cosmetically excellent, all original parts, no bent shafts. You likely won't find a cleaner set.
Set 663: WWII era Kluson strip tuners with black buttons, commonly found on Gibson made Kalamazoo, Cromwell, and other Gibson house brand guitars. The set is in good condition with little degradation to the plate surfaces, no bent shafts, and the buttons are in great shape. They don't look quite as old as they should but they don't look brand new either, not really sure if they are replacements or not. Barrels measure 1/4" diameter. No bushings or mounting screws available with this set at the time of listing, if you'll need them please inquire.
Set 664: Late 20s/early 30s Dinsmore & Jager nickel plated strip tuners for slot head. This style strip tuner was found on some Martin style 28 guitars in the teens/early 20s though by the time this set was made Martin had moved on to using Waverlys for their slot head guitars. More likely that this tuner would be appropriate for a Weymann, Vega, Larson or other quality slot head guitar from the late 20s-40s. The set is in excellent cosmetic and working condition with original buttons, no bent shafts. A little dirty but no corrosion and will brighten up with a good cleaning if a shiny look is what you are after. Rare set.
Set 668: 1930s Kluson strip tuners with the manufacturer's mark and patent stamp around the mounting screw holes on the show face of the plates. The plating on this set is very clean with only the slightest hint of degradation on the ends. Functionally very good, no bent shafts or other issues. Buttons appear to be original and are perfect. 12:1 ratio, 7/32” barrels. I do not have mounting screws or bushings with the set at the time of listing, if you will require these items please make sure to ask if I have them available at the time of your inquiry.
Set 669:  Teens/20s Waverly strip tuners in nickel with ivoroid buttons and gorgeous 'flowers and fronds' decorative pattern.  This set was used by Martin on guitars from style 28 through style 45 in the teens/ early-mid 20s.  The set is 'reverse gear', so not appropriate for guitars post dating 1926.  The set is in excellent original condition with no damage to the plating, shafts or buttons.  The set currently has barrels for solid head mount (Gibson used these for the Style 0 Artist, some Style U Harp guitars, etc), but I have barrels available to convert the set for use on a slot head guitar.  When inquiring be sure to specify which barrel set you will need on the tuners. 
Set 671:  1930s Waverly WG-31 "oak leaf" stamped tuners for slot head as were found on style 28 and higher end slot head Martin guitars of the 30s.  This exceptionally rare set has one button that shows a small crack but is very solid, the other five buttons show some color from age but are in good shape.  The nickel plating is super clean and bright.  All of the gears are original, the buttons appear original as well.  All of the gears and barrels turn freely with no tight spots or other functional issues. 
Set 672:  Teens/20s Dinsmore & Jager or Waverly (not sure which) strip tuners in nickel plate for solid head tenor guitar, probably off a Gibson.  The barrel spacing (center to center) is 1 29/32".  The plates have cross hash stamped decorative marking up either side and small, round off-white polished buttons with a sort of marbled coloration running through, unusual and cool.  The set comes with original bushings, I don't have the mounting screws, if you'll need some inquire at purchase and I'll see if I've got some on hand at that time. 
set 681: Rare 1930s Waverly WG-31 tuners for slot head with 'oak leaf' decorative pattern and ivoroid buttons. This set is in excellent cosmetic and functional condition. The plating has a little dirt accumulation from 90 years but I've left them as found, would clean up for a very bright look if desired as the plating is in perfect condition. Very hard set to find.
Set 684: early 50s Kluson deluxe “no line” individual tuners in nickel finish with metal buttons as were found on many Martin style 28 and 18 guitars of the era as well as other quality brands. The set came off of a completely trashed '53 000-28 that came into my shop over a decade ago. They are in good working order, the plating shows no degradation and the buttons are solid with no cracking. Complete with original bushings and mounting screws.
Set 686: Rare 1930s Waverly WG-31 tuners for solid head with 'oak leaf' decorative pattern and ivoroid buttons. Found on some Gibson style O 'Artist' model guitars, L-2 and Nick Lucas guitars of the 20s and 30s. I also have proper barrels for converting this set for use on slot head guitars such as the rosewood 12 fretters of the 20s and 30s made by Martin that used these tuners, so if you need this set for an old style 28 or 42 slot head let me know and we'll swap the barrels. This set is in excellent functional condition and is exceptionally clean, looking almost new. I have not cleaned them, they are as found. Very hard set to find.
Set 688: early 70s Grover stay tites, excellent condition functionally and cosmetically with original bushings and mounting screws.
Set 689: 1960s Kluson deluxe 'double line' strip tuners with plastic buttons, found on many Gibson and Epiphone guitars of the period (both electric and acoustic). The set is in very good functional and cosmetic condition, original buttons, bushings and mounting screws. Plating is clean with only slight pitting on the edges of the plates.
Set 694: Late 60s/70s Grover Rotomatic “Milk bottle” tuners in gold finish...these were found on late 60s and early 70s Martin D-45s as well as style 40 and 42 guitars in D size, along with some higher end Guild and other brands. The set shows a fair amount of plating wear from use but seem functionally fine. All of the washers, hex nuts and mounting screws are original. 
Set 698: 1960s Kluson Deluxe individual “double line” tuners with plastic buttons (nickel finish) as were found on many Gibson, Epiphone and other quality brand guitars from '65-'69. The set is in very good functional and cosmetic condition with original buttons that are not shrunken or otherwise compromised. The bushings are modern replacements of the proper style, Mounting screws not pictured but included.
Set #700: One set of 50s/60s Waverly strip tuners for solid headstock guitar, these were found on many Gretsch, Harmony, some Guild and other quality brands. The base plates are nickel plated and have single 'hash mark' decoration on either border. The buttons are plastic. The set has all of its original gears, buttons, cap screws, barrels and mounting screws (not pictured but included). No bushings available. Functionally and cosmetically excellent.
Set #704: 1950s Waverly individual open gear tuners with nickel plating and plastic buttons.  These tuners were found on style 17 Martin guitars of the 50s and 60s as well as many Harmony, Gretsch and other brand guitars.  The set shows some plating wear and they're a little dirty from years of use but would clean up nicely if a brighter look is what you are after.  All the parts including the buttons, hex bushings and mounting screws are original.  The set functions smoothly.
Set #705: 1930s set of Waverly strip tuners for solid headstock as were found on some Gibson L-0 and L-00 guitars of the period as well as guitars made by other quality manufacturers.  This set has nickel plating and off white buttons, all in very good condition.  There are no bent shafts or other functional issues.  The buttons are in great shape. One of the original nickel barrels has been replaced with a brass barrel of the exact same length and diameter (from another set of the same type/period), all other parts original. Mounting screws can be supplied if needed.  If you will need bushings please inquire as to availability.  
Set 706:  Super rare '46-'47 Grover "clover plate" open gear tuners as were found on some Martin 000-18, 00-18 and other small body guitars during the immediate post war era.  These same tuners also appeared on some popular lap steel guitars by Gibson, Epiphone and other manufacturers.  The set has one treble side that is not original to the set but is identical to the other five with the exception that it has a patent number stamp on the plate and the blocks that secure the worm gear/button shaft are square in cross section as opposed to rounded as on the other five.  All gears, barrels, buttons and screws are original and in excellent condition, no bent shafts, plating loss or other issues.  I do not have hex bushings at the time of listing but if you'll need them inquire as I may have them at the time you buy (same  with mounting screws).
Set #707:  1935-early '37 Grover G-98 individual tuners with nickel plating, 6:1 ratio and 1/4" barrels.  All of the gears, cap screws and barrels are original, mounting screws are old/period but not original to the set, hex bushings are modern replacements. The plating on the plates shows some loss/pitting/corrosion in spots but is much better condition on the barrels and buttons. The tuners all turn freely and smoothly without binding or tight spots. Found on many of the most collectible golden era Martin and Gibson guitars.
Set #710:  60s/70s Van Ghent in-line tuners for right hand headstock as were found on some Hofner, Gretsch and Hagstrom guitars.  This set is in very good cosmetic and functional condition, the only slight corrosion being on the button stems, the plates show no corrosion or pitting and the tuners turn freely and smoothly.  Since photographing the set I've discovered three hex bushings that are correct for the set so though they are not pictured, they are included.  No mounting screws.
Set 714: 50s/60s Waverly individual tuners with metal buttons, these were found on Martin 0 and 00-18 model guitars, many Gretsch and Harmony guitars as well. The set is in excellent function and costmetic condition, no plating loss or corrosion, all original parts, no bent shafts or other issues. 
Set 715: WWII era Kluson individual tuners with original off-white plastic buttons. This tuner was used by both Martin and Gibson on the majority of the guitars they made during the war era. Most of the guitars that used this tuner had them mounted with no headstock bushing, so none are being offered with the set. If you will need bushings for use with your guitar let me know and we'll discuss what would be right for your guitar and see if I've got what you need. The set has all original parts and is in good working and cosmetic condition.
Set 717: 1970s Grover “Slimline” (yes, believe it or not, that's what these bulky tuners were called) tuners for solid headstock 12 string. I know that these tuners were used on Martin D-12-18 and D-12-28 guitars in the 70s...likely appeared on other brands as well but I can't saw what and when. This set is in excellent cosmetic condition and appear to be in good working order as well. I do not have bushings or mounting screws.
Set 718: Modern “CF Martin” logo gold finish open gear tuners, likely made by Grover. These were used widely by Martin in the 90s and 2000s, not sure if they are still using them today. This set is complete with hex bushings and mounting screws.
Set 719: Late 60s/early 70s Grover G-98 tuner set with 'chicklet' buttons. Found for a few years on Martin 0 and 00-18 model guitars and also on many Guild guitars during the same era. Good functionally and cosmeticlly, no bushings or mounting screws.
Set 720:  Rare Waverly "bent tab" strip tuners for slot head guitar from the late 20s-30s, this set has barrels for slot head mount but I have barrels available to convert the set for use on a solid headstock guitar if that's what you need.  The set has all of its original parts and is in excellent condition, the buttons are perfect, no bent shafts, all the tuners turn smoothly.  As a slot head set these were found on some 12 fret style 17 slot head Martins (in size 1, 2, 0 and 00) and with solid head barrels they were used on some 14 fret Martin style 17 guitars (0 size) as well as some Gibson L-00s, L-0s, LCs, etc.  I do not have mounting screws paired with the set, if you'll need them make sure to ask when you inquire about the set.
Set 721: 1930s Grover G-98 'sta-tite' style tuners with off-white/ivory colored celluloid buttons (not grained ivoroid). The tuners have a 6:1 turning ratio, so they probably are '35- early '37, as Grover went to a 12:1 ratio by sometime in late '37. The set is entirely original including mounting screws and hex bushings.  All the tuners turn freely, no bent shafts.  The nickel plating shows some light wear/corrosion along the edges in a few spots but mostly they're just dirty from decades of use.  I have not cleaned them.  These were used on some Gibson L-1 and L-2, Nick Lucas, LC and archtop guitar models, the Roy Smeck Radio Grande and Stage Deluxe, as well as other quality brands.
Set 722:  1950s/60s Waverly strip tuners for slot head nylon string guitar as were found on Martin classic/folk models of that era (00-16C, 00-18C, 000-28C, 00-18G, 00-28G, 00-28C).  These tuners were also used on Guild Mark series classical/nylon string guitars, Harmony guitars, Gretsch, and others.  The set has all original parts and is in excellent condition, no plating loss or bent shafts, excellent functional condition as well.  I do not have mounting screws paired with the set, if you'll need them make sure to ask when you inquire about the set.
Set 723:  1940s/50s Kluson metal button open gear individual tuners for tenor guitar (set of 4).  The set is in excellent functional condition, all the tuners turn freely with no 'slop' in the fit of the gears.  The nickel plating is in good condition, it shows slight pitting in a few locations but is overall in very good shape though it is under quite a bit of dirt from decades of use.  Would clean up nicely for a brighter look if that's what you are after.  Barrels measure 1/4" diameter.  I do not have bushings or mounting screws paired with the set, if you'll need them please make sure you ask when you make your inquiry.

Set 724:  War time Kluson individual open gear tuners with plastic buttons as were found on virtually every 14 fret Martin guitar during WWII and many Gibson models as well.  This set is exceptionally clean, no corrosion or plating loss, no bent shafts or other issues.  The buttons appear to be original, quite rare as these Kluson buttons are notorious for shrinking and crumbling. No bushings with this set, as typically these were installed without them.  No mounting screws paired with the set either, but if you'll need a set let me know at time of inquiry as I can likely supply a set.

Set 725:  1960s Waverly strip tuners for slot head 12 string guitar as were found on the Martin D-12-20, some D-12-35 guitars, as well as other brands.  All original parts, no corrosion or bent shafts, excellent condition all around.  No mounting screws.
Set 726:  RARE and very clean set of 1937-1942 Grover G-93 tuners as were found on most pre-war Martin D-18s along with many other Martin models as well as many high end guitars from other quality manufacturers.  The set has no plating loss, no corrosion, no functional issues.  Hard to find a set this clean.  Original period Grover  hex bushings and mounting screws not pictured BUT ARE INCLUDED.  12:1 ratio, 7/32" barrel diameter.

Set 727:  1960s Waverly strip tuners for slot head 12 string guitar as were found on the Martin D-12-20, some D-12-35 guitars, as well as other brands.  All original parts, no corrosion or bent shafts, excellent condition all around.  No mounting screws.

Set 728:  1950s/60s Waverly strip tuners with large barrels for slot head nylon string guitar as were found on most Martin C and G series guitars (00-18C, 00-28G, etc) during that era.  Also used on the Guild "Mark" classical guitar series and others.  These are in excellent condition cosmetically and functionally, all parts are original, no corrosion or plating loss.  No mounting screws.

Set 729:   Beautiful set of 50s/60s Waverly WG-31 slot head strip tuners as were found on Martin 0-16 NY, 00-21, 00-21 NY, D-18S, D-28S and D-35S.  The set is exceptionally clean and functionally excellent.  All of the gears, barrels, cap screws, buttons and mounting screws are original.  Understated elegance.

Set 730:  1960s/70s German-made Kolb strip tuners for slot head guitar in gun metal finish with fancy engraving and pearloid buttons.  These tuners have solid brass buttons suggesting that they were intended for steel string guitar...the only steel string guitars I've seen these on were the very few 00-45 and 000-45S models that Martin made in the early 70s (used to own one that had these tuners).  With large barrels for nylon string these were found on many high end classical guitars of the era including those built by Papazian.  The set is in very good cosmetic and functional condition.  No mounting screws.

Set 731:  1950s Waverly WG-31 slot head strip tuners as were used in the 50s on the only slot head Martin was making, that being the 00-21.  In the 60s they used these also on the 0-16 NY, 00-21, 00-21 NY, D-18S, D-28S and D-35S.  The set is in very good condition with minimal wear to the plating.  No functional issues, all the tuners turn freely with no tight spots or binding.  All parts original.

Set 734:  1930s Kluson open gear individual tuners with off white plastic buttons, these were found on some Gibson, Martin and other quality brand name instruments in the 30s and early 40s.  The tuners have original nickel plating in very good condition, all the gears, barrels and cap screws are original.  The buttons are all replacements from Antique Acoustics, the most accurate Kluson button replacements.  12:1 ratio, barrel diameter is 7/32".  No bushings or mounting screws.

Set 735:  VERY RARE set of 6 Grover banjo tuners for guitar as were found on Martin's earliest OM-18, OM-28, and OM-45 guitars. The set has all of its original parts and is in excellent condition cosmetically and functionally.  Also occasionally found on some Gibson L series and Nick Lucas guitars and 6 string banjos of various makes.
