I also think it is Romanian made. From wiki:
Romania
* Triangular shaped markings, some with an arrow inside, on many components of the rifle. Normally three “R”’s surrounded by crossed stalks with leaves pointing outwards are on the top of the breech. Year stamps are quite visible.
* M44 Pattern Domestically produced version of post war pattern Soviet M44 Carbine during the years 1953 to 1955. Variances to the Soviet pattern produced minor differences.
Mine has the triangles, with the arrow inside, but no “r”s or crossed stalks.

See post 42 for arsenal markings.
Romania only from 1953-1955.
The triangle/arrow is the Russsian Izzy
This it?
