The Kiev rangefinder cameras were produced in several different models, many of which have variants and sub-variants. This plethora of cameras can make identifying a Kiev a bit tricky at times. Luckily for us, this Kiev 4M is a Type 3, a designation reserved just for the Olympic models produced between 1979 and 1980 for the 1980 Summer Olympics held in Moscow, USSR. There are two sub-variants of the Type 3 though. According to online sources, this Kiev 4M pictured here is the Type 3b due to the white striping on the rewind knob. The Type 3a apparently has the old style, solid black, rewind knob... for what it's worth.
The serial number on this camera is 8001017, indicating it would have been produced in 1980.
