Nice gun. Please picture or describe the receiver markings and barrel proofs. Also is this a 100% serial number matching gun?
Yes, it's an all original German Mauser.
Receiver Markings:
The meaning of the proofmarks:
U with crown means: Endbeschuss/final prooffiring
B with crown means: marking of foreign weapons and that is a little bit strange since the gun was made in Germany but probably reimported from a foreign state
G with crown means: rifled barrel
N with crown means: nitro powder proofed
