Likely a Bavarian depot then. Explains the bolt!Nothing else on the butt plate I can see.
The striker assembly gives me pause, but I think the body is Ok.It’s a great rifle! Though, I suspect the bolt has been humped. The font looks off and the small bolt components weren’t renumbered 99% of the time. I leave 1% open because anything is possible. With that said, I’ve never personally seen it and would expect small components to take the form of an overstamp rather than grinding. Again great rifle, the remainder looks righteous, I just think the font is suspect.
