These came off of a parted old fender jazz bass not sure about the year They are gold plated and are the reverse style All original complete set, Come with bushings and screws. Great working condition nearly mint. This are Kluson 546 tuners which were indeed used on Fender Basses and Gibson Thunderbirds. The gold-plated version is very rare, as that was a custom option to order a Fender with gold hardware.I'd date them in the 1963-1965 bracket.*if you wonder how rare: I'm keeping an eye on the vintage market for about a decade now, and I've only seen 3 original gold-plated basses for sale in that period.
Take a look at all very clear photos and ask any question you need.
