Seeking advice. I have recently received a pre-war FED 6.3/100 lens. The glass is in excellent shape, but there are issues. The focus helicoid is very stiff and needing to be cleaned and re-lubed. In addition, the lens does not focus to infinity (on a Sony A7II) where the 'infinity' focus is about 100 ft. For the last five years, I have sent all of my lenses that needed work to Youxin YE, but Youxin will not work on Soviet equipment. Therefore I am seeking advice from members of this group on who to turn to in the U.S. for the necessary CLA. It would be even better if you could recommend a source who would also be able to shim the lens to work on an actual Barnack. Thanks.
