In 1941 M-72 production began in Moscow (ZiS), at the end of 1941 equipment was moved to Irbit, where IMZ appeared. Some amount of M-72 has been produced in Gorkii (repotedly only assembled from Moscow parts).
Since early 1950's - available in shops. Before that time they were only for army.

My great gratitute for kind contribution to M-72 specialists:
