Kluson Deluxe 3-in-line tuners, aged relic finish Purchased new about 20 years ago. These were installed on a Gibson vintage Les Paul Jr. All strings' shafts are straight, and there are no issues with movement, but the turning torque varies. Tuning accuracy is not great. While they have a dignified look due to the relic finish, there is considerable rust and dirt. Reference (amateur measurements) Shaft post height: 25mm from the plate Shaft post diameter: 6.3mm Bushings: Inner diameter 6.4mm Bushing top diameter: 11mm Bushing bottom outer diameter: 8.8mm Plastic buttons: Glossy white Tuners, 6 bushings No mounting screws Original Kluson box included Sold as-is, no returns. Thank you for looking.
