Lol, I’m not understanding the confusion. Are my posts not visible? Rifle was not manufactured into a complete rifle during world war 2. Wartime production stopped in the “a” block. Yours is a “d” block. So it was assembled post war using “some” wartime made parts. Specifically the parts that have the “little waffenampts”. Like I mentioned before, it would most likely have the standard looking post war Czech stock and most likely the winter style triggerguard.
The firing proofs are the little rampant lions stamped on the left side of the receiver and barrel. That’s the biggest giveaway as if it was a German WW2 produced example, those lions would be small eagles with swastikas at their feet.
You say you don’t want an original but maybe a repro because you plan to shoot and don’t want to beat it up but also want it as “living history”. The most living history period accurate would be the post war Czech stock like I’ve mentioned several times because it’s the way it was built and has a unique stock configuration (semi kriegsmodell). Something to stick it in and shoot would be like
@Cyrano4747 mentioned. Just any k98k stock that is solid. You bed it/shim it and shoot at your hearts content. For a repro, I only trust Leczek Foks in Poland. That will cost you handsomely, and the wait times currently are excessive. Been a few years since we’ve done business.
Czech firing proof below. Is your triggerguard like the one on my example? Post war Czech stock. German wartime firing proof for comparison.
