Ted I changed the heading just for you! No reveiver markings, except small box marking also seen on barrel shank. Canadian import so no US import marking on it, probably out of Syria or Egypt. The only reason I bought it, is because of the unknown marking I had never seen before. Serial numbers match 31395 on all major parts.
Jean, that looks like the M44 that was at the Ancaster Gun Show on Sunday. I looked it over, noting the Arabic markings, but was unsure of the barrel stamps. The young lad sitting behind the table new nothing about it (seemed quite bored) and the owner was strolling around and not to be found. Could it have been rebarreled in the Middle East?
I passed on it, but finally found the Soviet M40 helmet (size P2, Leningrad Metalurgical Factory, stamped 1948 in very good plus condition ) I had been looking for. Interesting catch. Remove the stock and let us know what you find.
The barrel markings look very similar to that of the East German company Suhl that made barrel for the 91/30 rifles used as snipers in the DDR and rebuilt there. I'll post a picture of a DDR made barrel for you with the markings. I don't know what the RWD stands for but the serial sequence is very familiar.
