Mir, vintage rangefinder film camera
35 mm, M39 (LTM) mount
s/n 6027006, late type
Krasnogorsky Mechanical Plant (KMZ), Krasnogorsk, USSR, 1960

Very good condition. Shutter works properly except 1/30 and B (at thess speed shutter fires as B and the first curtain moves a bit lazy). Shutter is cocked with effort. Self-timer does not work. Body has signs of age and use. There was an abrasion area at the shutter curtain, fixed with insulating tape (see the last photo).  Lens is not included, body only. Take-up spool is included.

History of the camera
"Mir" (in Russian, translated as "Peace") is a Soviet rangefinder camera made by KMZ since 1959 till 1961. Totally 156 229 pieces were made.

It is a simpified version of "Zorki-4", difference is in reduced shutter speeds: 1/500-1/30s instead of 1-1/1000s at original model.

Otherwise it is the same "Zorki-4". Body is made out of aluminium, rear cover is removable. Base of the rangefinder - 38mm. Rangefinder is united with viewfinder which has dioptric adjustment.

Camera has a self-timer, cold shoe, synchrocontact for cable flash. 
Tripod socket is 3/8".
Default lens is "Industar-50", 3.5/50, or "Jupiter-8", 2/50. Of course, all lenses with M39 (LTM) mount fit this camera.

There are two variants known: with prominent frames around viewfinder and rangefinder windows on front panel (early variant) and without them. Here I offer late variant.
