Thank you Bill for supporting my line of thought, and that's exactly what we can do is recreate the situation to the best of our knowledge but I know that I can't probably even imagine the harsh reality. One other thing I was thinking too that it was probably a very different factory also once it moved to Berdsk since most likely most of the boys (I'm sure girls too) working in the commune were called up to serve in the war, so production of FED was probably mostly taken over by local Berdsk population, losing the camera works expertise in the process.. once again just speculation for discussion's sake..
Also I found an article where one collector claims that BRZ (Berdsk Mechanical Factory) was the factory that accepted FED in Berdsk during evacuation and that 500-1000 FED Berdsk were made there as well as FED-B - a Leica III copy, but the journalist writing the article didn't find any examples of the Berdsk war-time made cameras in the local museum. Here's an auto-translated fragment of the article:
Publisher of the "Wedge" Vadim Komarov collects cameras. An online auction "Molotok" he bought the camera "FED-B", made in the walls of Berdsk radio factory during World War II. Until 1941, the production of cameras has been established at the Kharkov plant, which at the beginning of the war were evacuated to Berdsk. It was believed that the production of cameras stopped. However, Vadim Komarov says that in 1941-1942 the plant produced 800-1000 cameras. According to some reports, beginning in Berdsk produced model "B" - a copy of the camera «Leica III», which adds long-term exposure.
Abbreviation FED means Felix Dzerzhinsky. The first models were produced in 1934. At the end of the 30s produced the so-called second model, it "FED-C" or "commander FED", which was supplied with the lens "FED" 2/50, the shutter speed range has been increased - added shutter speed 1/1000 sec. C 1938 to 1941 produced a modification "FED-B" or "the general's FED", with extended excerpts from 1 sec to 1/1000 sec.
In Berdsk Historical Museum of Art no models were found made in Berdsk during the war. Chief curator of funds Tatiana Ovchinnikov stressed that the special value of the fund collection are "FED" and "press photographer" pre-war years. One of the exhibits found in the garage, took out one berdchaninu inherited. He was there collecting dust forgotten by all. The most surprising is that the camera is a mechanism that allows you to stretch, like a concertina mechanism. Thus conducted focus is activated. "Fotokor-1" was produced from 1930 to 1941. These cameras have become the primary means of shooting by courtesy of the Great Patriotic War.
