The Start was KMZs attempt at a profession grade 35mm SLR. They were produced in the early 1960s and maybe 1959 IIRC. Several interesting features: removable prism so a waist level finder could be used, Bayonet mount for the lense, film cutter so one could use a empty cartridge as the takeup reel and change film in mid rolls, glass prism instead of mirrors, support for two different types of flash, polished glass pressure plate. DOF preview, 1/1000 sec shutter speed etc.
This example was made in 1963. Unfortunately, it is not usable. The pressure plate is missing and the mirror does not stay in position. Also the mount is loose from use. It must have seen lots of use for that to happen.
