Looking for a set of (2) 7x15 and (2) 8x15 early 1970's Fuchs - I believe these came with 3 prong caps and that is what I would like. Can be restored or un-restored, either is fine, preference to the latter. Happy to buy pure, also happy to trade. Let me know either way. In trade I have a great pair of Silver Dot Talbot Berlin mirrors, with the traditional cone base and the rectangular lens.
