I have two sets of tuners, they're old, and I believe one is gold Kluson sealfast tuners, as found on the Gibson Johnny Smith and Super 400; at least they look exactly like the pictures I found of these guitars. The other set is identical except for the knob, which has a small bolt at the top, a different shape, and a plastic bushing where the knob meets the body of the tuner.
Can anyone tell me what I've got? I've attached pictures of front and back. Does anyone know if there's any kind of guide to old guitar parts? I've googled 'til the cows came home, but no luck.
While I'm at it, I'm attaching one more picture of two miscellaneous tuners I have that I think may be Kluson wafflebacks, but again the knob doesn't match the pictures I've found.
