Nice Zenit camera produced by KMZ, Krasnogorsk in 1955. It is the first camera in the Zenit model series, rather uncommon nowadays, don't confuse it with much more common Zenit-C. See more information at http://sovietcams.com/index.php?-827463118 . The lens is a rigid version of 3.5/50mm Industar-22, also much less common than the usual collapsible rangefinder versions of the same name. The camera is used, you can see the signs of usage on the photos. Black paint on the body behind the lens is partially rubbed. No bad scratches or cracks. Seems to be working. The shutter speeds work but cannot say if all of them are accurate, I did not test this camera with a film.
