SNIP ... The Zorki 4 i read that is more reliable, have a better viewfinder and is a copy of the Leica...
Just for the record; FED cameras made in the 1930's are copies of the Leica model II but that factory (FED) stopped making them in 1941, perhaps when Germany invaded the USSR.
What's more; the Leica model II was really only made in the 1930's. Some were made in the 40's but only a handful compared to the factory's output of the later models. I suspect they were using up spare parts as, for example, the entire output between 1941 and 1948 was 347 model II's. So the early FEDs etc are copies of
a Leica not
the Leica. (Strictly speaking and based on adverts from that time, the expression "The Leica" was used for them during the 1920's. Then came the model I and so on.)
Production started in the USSR after the war but by then the USSR engineers had time to think about things and so the cameras are best described as based on
a Leica. As time went by more and more innovations were added to the design and so late FED and Zorki model 1's drifted away from the original Leica design. BTW, look closely at a 1938 FED and you'll see the changes creeping in on the shutter button.
You only have to look at the FED TSVVS & 2 and Zorki 1B (all 1949 onwards) to see how this main trend started.
It's usually when people are selling their old cameras that the story that any FED, Leica or even Leningrad or MIR is a Leica copy is dragged out, polished up a bit and repeated. The moral is; don't believe all you read on the internet, including this, but do some proper research and ask on RFF.
