I recently purchased a deactivated PPSh 41 produced in 1945. Since I am new to this gun, I tried to locate the reciever markings on the site www.ppsh41.com , but I did not find it there. Therefore I am wondering if anyone of you can help me. It is marked with 1945, and under something that can resemble an A with e flat "top" (might be cyrillic) and an E. On the right side of the gun, in front of the magazine well (near the barrel hinge) I see a stamp that resemble the letters TRA.

I hope someone can help me

Best wishes
