Hello,
could anybody tell me please, how can I find the year of production of my CZJ Tessar lens?
On the front ring of the lens is: Carl Zeiss Jena Nr.2814331 Tessar 1:4,5 f=18cm
On the side - N51
Thanks
Alexander

1942 or so.
Anywhere between 1942 and 1948 - they hit the 2.7 million in 1942, but they numbered lenses by batch, and by the later war years, many batches were postponed, with some numbers reused in the post-war period.
