hey phaethon i finally did some research on it, I never really looked at the rifle much in the past just set it in the back of the safe and kinda forgot about it. anyway it is from the tula arsenal, but 1933 was its 3rd lowest production year, only beat by 1930 and 1935, and in 1933 the Izhevsk arsenal turned out 29,312 more rifles than tula. also my bolt is the only part non matching, it is from the Izhevsk arsenal, however i can not decipher any other markings on it. However I do not have a refurbishment mark on my rifle. I do have what I think is the firing proof mark, however my rifle is in excellent condition, not a single bit of wear or anything inside the rifle. The rifling is very sharp, I dont know how else to tell if it is shot except for wear and tiny scratches, and those sort of things. I also have never seen another laminate stock in person, I dont really look for these rifles though. Also im sure the slings are common but I never see those either on the rifles I see in gun shops. These rifles are pretty cool to learn about, I wish I could find out what all the markings mean, I have looked all over the web and I find lots of marks, just not the ones my rifle has
