Hello,
I was a bit surprised on dismounting the front part of my Kiev II serial # 503737.
At the reverse of this part, some traces, as if one had wanted to wipe something. "Kiev" was perhaps stamped too hard? The same circular traces can also be seen on some 1947 Kiev to wipe "Contax", that time!
And, close to the selftimer, but on the lens plate, a number: "3536".
Thanks if you have explanations.
Amitiés; Jacques.
