As a side note to those comments on soviet cameras:

The original manufacturer of the Zenit cameras, KMZ, manufactured 20 million cameras, out of them 15 million Zenit.

In Addition a great number of Zenit cameras were manufactured by Belomo, including Zenit cameras totally independantly designed and made from KMZ.

The camera in question is a Belomo design and product, though based on a KMZ model.
