I need the four black rims for rangefinder/viewfinder which can be found on the early fed 1 up to # c. 10000. When I say "black", they are rather yellow brass nowadays. Impossible to find them as parts, and I want to restore a 1a.
Really hard to find them. I never saw them separately without a camera. I have FED 10xxx (I don't have the camera here and I don't remember serial) with this black rims. And I had FED 11xxx with regular chrom rims. I wonder when there was a change from black rims to chrom rims.
Certainly the limits are a bit uncertain, like for all the changes during the 1a/1b period. Many 1a had to be repaired, and certainly many of them were "improved" with chromed rims at the same time. It's the case of one of my 1a-s... And I personally have the same limits in my collection: black rims before c. 10000, chromed after c. 11000.
