Kiev II 1950

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.

You are right, Jacques.
It was tried to wipe "Contax". Some Contax parts was still used on Kiev cameras until 1953.
The number 3536 ist the factory number of this part of the camera. The single parts could be
produced separately on different factories and they had own registration number. I think 3536
is also such registration number of this part.

Regards, Alexander

Until 1953, you are sure?
I thought of 1950 or 1951 for some parts (of Kiev III, for example).
Thanks, Alexander.

Amitiés. Jacques.

I saw exactly the same traces on the front plate of my Kiev III from 1956 (export version). I think the name was stamped too hard.
