As with other Soviet-era rangefinders, the Mir's shutter speed selector rotates when the shutter is released, and should not be changed until after the shutter has been cocked. If you change the shutter speed without cocking the shutter first, the setting pin can be broken when you advance the film and cock the shutter.
The Mir is slightly simplified version of the well known former Soviet Union) Leica inspired camera, the Zorki 4, lacking the slow shutter speed mechanism (it also lacks the fastest speed of 1/1000 second). Whereas the Zorki 4 was released for export from behind the iron curtain, the Mir was intended for internal consumption only.
It was offered with the Industar-22 50mm f/3.5, the Industar-26 50mm f/2.8, or the Jupiter-8 50mm f/2. Jupiter-8 is a KMZ copy of Zeiss Sonnar.
The Zorki-4 is a Russian Leica inspired camera that loosely based on the Leica II/III.
