I am looking for an uncoated Fed 50mm 3.5 lens with the old aperture marking range (3.5 4.5 6.3 etc) to match a camera of the Fed 1f series.
They are not common to find on ebay at the moment. Tips would be gratefull.
Also looking for a parts Fed 3.5 lens with the modern markings to 'fix' a lens which has been re-engraved as Leitz. In fact: every parts Fed 3.5 lens is welcome.
