52 stands for 1952, so that’s post war weapon.
oof was hoping that it just naming thing like with mp717r
The dust cover looks SKS/SVT like so yeah its definitely after the war but there are tons of Czech semi autos that were made like ZK 381(38 meaning year 1938 and 1 being model 1 )(There was a version(ZK 381 AU II) in 7.62 by 54 R which Russians tested it had a curved mag )(Normal one uses 8 mm mauser but both versions have 10 round mag)
OR HB rifle ( Holek-Beneš semi-auto rifle )(Mag fed but mag was not preserved but apparently it was 5)
There is also very cool Automatic rifle that Imma keep it secret for now but it was inspired by fedorov and it looks a lot like it
yea especially the front and that smooth metal on the body
never judge a book by its cover, you would think at the very least they would have cut down on the weight the thing looks heavier than a Garand
