Your two pre-war Mosins are still wearing the additional mill cuts on the side of the receiver. You will note that your 42 wartime rifle does not have them.
After the invasion in 1941, the Russians started eliminating superfluous milling and time wasting finishing.

My 38 Tula fits the inletting closely in that area. My guess is your 38 is in a later replacement stock.

Most, not all, Mosins have been re-arsenaled at least once before they left the former Com-Bloc.

Several machining operations were eliminated on the wartime guns. Note that the left receiver rail on the wartime gun has no scallop, and that the right rear of the receiver is not beveled to cosmetically match the bevel (for clearance of the safety) on the other side. The narrowed section at the tang was eliminated. Wartime receivers were also bored straight through on the front, with the barrel only locating on the end of the receiver, as opposed to abutting a second surface inside the receiver.

When the guns were refurbed post-war, late guns always went into late stocks, and early guns sometimes went into rehabilitated early stocks and sometimes into late stocks.
