I am new of this grup, and I would have a question to expose: I am the lucky possesor of a Super Ikonta IV and a Contessa 35, I know the first one was produced from 1956 to 1960 and the second one from 1950 to 1955, but what I would like to know is the exact year of production of the cameras.?The serial number of my Super Ikonta is D92172 and the lens (Carl Zeiss Tessar 75mm f/3.5) serial number is 1303498, the ones of my Contessa 35 is A10345 for the body and 862835 for the lens (Carl Zeiss-Opton Tessar T 45mm f/2.8); there is a way to date accurately our Zeiss Ikons?
PS. I also have a Rolleiflex 3.5 E of which I would like to know the exact year of production, the serial of the body is 1751186, the lens (Carl Zeiss Planar 75mm f/3.5) is 1764128
I rely on your knowledge to?give a precise age to my "old ladies"
