TOKAREV Cartridge manufacturer & 762x54R

Does anyone have knowledge on this manufacturer…H 111 made in 1949.

Also a very similarly marked cartridge but G 121 made in 1948

Edit: I think the G one is: The Mechanical Factory Sadu S.A, Bumbesti-Jiu, Gorj, Romania, can anyone confirm

Thanks Members

Excellent headstamps!
As per the current state these are Romanian and the exact manufacturers are not identified.

The “H” exists also in a 3x120° configuration: H 111 51
