Here's a Gibson Tunamatic bridge in chrome with the thumbwheel adjusters and mounting studs.
It's in very good shape and please keep in mind that these pictures are more than twice actual size.
This bridge was taken off some instrument during the late 1970s so the bridge is of some vintage
before 1977and has the small diameter mounting screw holes of that era. In 1977, Gibson
switched to the larger mounting hole system for Tunamatic bridges.
Asking $35, includes U.S. or APO shipping.
With Thumbwheel Adjusters & Mounting Studs
Pretty clean, but not perfect.
