Passport of the pictured camera shows odd data:
Camera is made in 1981 with serial 14.174, but according to KMZ only 105 were built in 1981!
Lens is made in 1982 so was this specimen counted into 82-production of 19.760 cameras?
And it was sold as late as in 1985!
Also price was reduced 1. Dec 1983 to 102 rubles, discount sale in USSR?
