Timur, nice start to a collection.?? I am of the opinion that the
268 lens is probably post-WW2 production.? I have a lens with a
close serial number, and it has a mix of brass and aluminum alloy
components.? Also my lens had hand-scratched markings on the
internal lens barrel that are not typically seen in earlier CZJ
lenses.

Thank you very much Mark,
Very interesting, my mother was born in 1936, my father in
1938, my father in law in1937, my mother in law
in 1945. My self I was born on December 4, 35 years later
after the 2859561 batch was completed.
Thank you,
Timur
