Sorry, I can't pinch photos from a published book. The example looks like yours, but with intact stamps.

The rifle is basically matching, but the bolt assembly is a mixture. This is not typical for a captured weapon for any regular army, as if a replacement or other captured bolt had been fitted, it would have been renumbered to match the rifle number.

This is probably a case of a rifle being confiscated after WWII, hence the erased Nazi-era stamps, and the person who handed it in may have deliberately "lost" the bolt, thinking "if I can't use it, no-one else is going to!"
