Grover Rotomatic Milkbottle Buttons 1970's - unsure on exact year - Gold

One set of grover milkbottle rotomatic keys (gold). These were pulled off a set of genuine grover rotomatics and were working fine when on the tuners. I'm unsure of their exact age but the patina matched the rest of the tuners. The tuners were bought for a project and the buttons swapped for a different set - so these are extra to sell. Would be great on a ton of Gibsons and Gretsches from the 60's and 70's.

Sold As-Is.
