Many thanks to Vlad in posting my article about Leningrad Cameras. To all of members interested in know more or contribute with new data I will be pleased in answer them, and add it to my article.
The final Leningrad model or third generation contributed to the advent of Werra, Second postwar Smena generation and indirectly to Belmira.
This third generation, is a magistral fusion of the Zorki 4 and the Finetta 99, with na addition of a self timer of its own. The Belmira is a poor man's Leningrad.
It is really notable how a camera itself tells the history of an era!
