Well, I brought my 1943 Soviet (Izhevsk) M91/30 home on Saturday. It's in pretty good shape overall. The wood is very nice. Lots of cosmoline has absorbed, giving it a nice sheen. The barrel looks good, nice rifling with no pits. I am concerned that the bolt and the magazine floor both have different mismatched numbers. I am more concerned about the bolt. Is my concern merited, or unneceessary in light of all the refurbishing that occurred? There is a "matching" serial number on the side of the receiver as well as the barrel-possibly an indication of a refurb? Any insight appreciated. I will probably take it to a gunsmith to have the headspace checked before firing. I have read some horror stories on some of the other sites in regards to peirced rounds and exploding bolts.
