Just from the pics, marking, and date. I would say no. But it could be. Need pics of the left side of the receiver. The sniper program didn't start until 1940's.
I feel you. I have only 10 cans left. When those are gone I dont think I will be able to shoot my PSL or mosins anymore. Check here or even armslist. Seen them as low as $110 to $150 this year.
Hoping the wars in the Middle east end. Maybe then we will get new shipments of surplus.
My Chinese Mosin type 53 is ok. You need a rubber butt pad if your for to shoot more then 5 shots with it. It will get the job done.
Sadly French MAS 36 and 49 are both very poor rifles. Its a shame, because they are very neat rifles.
