Regretfully KMZ did not manufacture stereo cameras, but the demand for this kind of technology was always there. That caused a lot of photo enthusiasts with mechanical skills make homemade versions of different cameras into a stereo unit by connecting two cameras together.

This is a camera from Dnepropetrovsk Stereophoto club in Ukraine. It is made by connecting 2 Zenit AM cameras into one Stereo camera. An amazing piece of work.
