I don't really concern myself with all matching either. I mean it's nice but if it takes a particular rifle out of my price range, I'll go with a mix-master with no second thoughts. US rifles seem to have been rebuilt numerous times. German rifles often had bolts mixed up due to unit regs on shipping them home or they are complete mix-masters based on rebuilds from the Sovieticon Union, Yugoslaviaicon or a few other nations post war programs. Japaneseicon rifles also have the bolt issue along with the ground mum issue to deal with. Britishicon rifles also went through rebuilds but they seem to have made an effort to re-serial parts and didn't number everything like the Germans did. The Soviets rebuilt almost everything. The Italians didn't mark much so problem solved there. It's a crapshoot. My K98icon is an RC with a 1944 receiver/barrel with an early flat butt plate stock. No clue on the other parts.

You at least have a date on the stock, that's a plus. Not sure if anything else is possible.
