I've had a Mosin Nagant 91/30 for about 20 years. I deceided to go through the safe and research some of the old WWII weapons. Mine is a Tula model 91/30 with 1940 year stamp. SA is stamped on the right side of the receiver and again on the left beside the serial number. The receiver is round and it has the Russian globe front site. The receiver and bolt have matching numbers. The mag well and butt plate are different. I found the Finnish "D" also stamped on top of the receiver. The metal and wood are excellent with very little handling marks or wear. The lower portion of the stock appears to be one piece. The barrel is bright and clean. I know you probably need to see the gun, but is this a Finnish capture 91/30 and is it more valuable than your basic 91/30?
I also have a Mod 44 from the IIzhevsk arsenal that had been refurbed at the Ukraine, dated 1946. It is in excellent condition.
Thanks for any information on these rifles.
