|197X Moskva 8M / Москва 8М 154519|
The decal on the back says "ZPM, Model 8M, gost 8274-71". ZPM could stand for something as simple as "завод пишущих машинкoв", or basically, typewriter factory. As has been addressed before, "gost" means a specification that any factory can build from. The "71" may mean that this was designed in 1971.
Here are all of the different variations of the Moskva that I've been able to find. This is the order that I think they were manufactured.
And the weird ersatz-German (could I resist?) keyboard.
