Anybody happen to have a couple (2) of the domed screws as pictured in the center of the gear? These were pretty much standard on the Rubner, Pfretzschner and other German basses from the 1930-1960 and also on many Kays, etc.
Would also ideally like to find the correct gears themselves as the ones currently on are newer replacements - but they work ok....
