Yep similar to the ones I posted the last two days. It is a Zorki 6. It is basically a Zorki 5 with a hinged back instead of the bottom loading of the Zorki 5. They were produced from 1959 to 1966. Hmmm, the Zorki 4 was in production past the sucessor of its successor? Yep leave it to the Soviets. Actually the Zorki 5 was based on Zorki 2S, so the Zorki 4 represents more of a fork in the road.
This one was made in 1962. It has a Industar 50 lens made in 1961. Hank helped.
