The Russian Mosin Nagant Forum

I'm confused about this MN Forum statement: Manufactured from 1939 to 1945 at the Izhevsk arsenal.
Manufactured in 1940 and 1944 at the Tula arsenal.
How did this rifle manufactured at Tula in 1895 become a M38 configuration?
I hope the photos are adequate to help.
Thanks

Thanks for the quick responses. Yes the serial number on the bolt is electro-penciled. And I've attached a photo of the shank markings.
Again thanks.

I am trying to determine what to call my Mosin Nagant carbine. Made in 1895, with a hex recvr, Tula shank markings, and a laminated stock. I read that hex receivers came after 1930. And I also read that the M38 was made after 1939. Four serial numbers match: receiver, magazine, butt plate and bolt. ...
