This is a factory Gray covering version of Zorki C camera. These are known to be made from 1956 to 1958.
The Zorki-C has a taller finder to accomodate the flash sychronizer. The rewind switch is now a collar around the shutter release instead of a seperate lever. It doesn't have a self-timer. Some camera bodies are covered with ribbed nylon in light gray instead of vulcanite.
