I'm hoping to find some info on Grover tuners that came with a lot of guitar parts. There are only 5 (wish I had the 6th), 3x3. The backs are marked Grover, with a star and Pat. Pend. USA cast on to a flat back.
The vintage Grovers I found on the net all had a round back with no star. There was a humbucker, stop tail piece, and a tune-o-matic bridge, so I'm assuming they came from an LP, or LP type guitar, There are no markings on the stop bar or bridge.
Any help will be greatly appreciated.
