Model 21 /1. 7.62 mm automatic rifle “ABC” designed by Simonov model 1931.
As the previous (see model 20/1), the rifle with the removal of gunpowder gases. Gas piston is located at the top of the barrel, the bolt is rectangular, the firing device of the striker type, locking - wedge. Sight sector. Bayonet blade. There is a translator of automatic and single fire. The magazine is inserted for 10 and 20 rounds. The rifle differs from the previous rifle by some design changes.
The rifle was developed by BNK and S. The main developer is S. G. Simonov.
The book “SOTILASKÄSIASEET SUOMESSA 1918—1988” provides a comparison of the AVS 35 and AVS 36. It says that a pilot batch of about 400 rifles was made, and among the differences from the AVS 36 is a different magazine. Although, what is rather strange, in the same book there are photos of the AVS 35 and AVS 36 with magazines, and visually the magazines are impossible to distinguish, most likely the differences were only in the magazine coupling system.
I mean, the AVS 35 could use 15-round magazines. I just wanted to point out that, other than a different clutch system, the magazines shouldn’t be any different, and in the case of a 20-round magazine, it should just be bigger.
Um… Well, these are essentially the same magazines, just different sizes, it wouldn’t make sense to make different magazines each time. Even Tokarev used Simonov’s magazine in his 1934 rifle.
1-4. CARABINES
Shortened and lightened rifles, which were usually used to arm cavalry and special branches of the armed forces, are called carbines.
Automatic carbines differ from automatic rifles essentially in that they have a shorter barrel and, therefore, somewhat lower ballistic qualities. Self-loading carbines were developed for both the pistol cartridge and the 1943 cartridge.
Sample 53/1. 7.62 mm self-loading carbine with powder gases and turning behind
the bolt, developed under the regular rifle cartridge. The prototype of 1934.
The carbine was developed in the ONK and S on an initiative basis by V. A. Degtyarev.

Ok I got it
So as we found - that is a 20 rounds magazine for AVS. Maybe one fully pruffed photo in whole world. Bless you
