Izhevsk 1941 barrel date.
The magazine/bottom metal is a forced match (struck out, re-stamp). The bolt and butt plate look like they might be "re-matched". Old numbers removed, new ones stamped. The butt for sure, the bolt might be, I dunno.
The bore has strong rifling, but is still full of crud. I never cleaned it from when it came. Looking it over now is only the third time I've ever had it out of the box.
Some flakes/chips in the shellack and some funkyness up front. Looks like they didn't strip it all the way and the stain/shellack didn't take. I'll try and get a couple quicky pics up.
