Hello
I've just bought one of these lenses. Serial number tell it is from 1954.
Shutter is copal 3 but it isn't its original shutter (max aperture is 4.5 instead of 5.5. See pic #1. I guess this can be corrected with the new focal lenght and shutter data.
But I'm worried about cells separation. I need to know how it is mounted other lenses like mine. I have several brochures about tele Xenar lenses. They say that total lenght (h1) is 110mm. Mine is 102.5mm (!). And rear leght to seat is 27.1mm. Mine is 22.3mm. See pics #2 and #3.
I wonder if can be different versions of this lens. I have different data on angle and IC as you can see in pics #4 and #5. One says 32 degrees and 206mm. Other says 35 degrees and 230mm. What a mess!
Csn somebody give me advice on this. Maybe I have to ad shims to get the correct distance...
