I’ve read in these pages that the pinged proofs is a sign of Romanian military use, after the russians drove the Germans out & the pro-axis government capitulated. Defaces it collectibly, but doesn’t affect the performance of the rifle, I have one.
What’s the question on the vz24? Serial # is correct pattern……. if you look inthe picture reference section under Brunn I & Brunn II, you’ll see similar rifles to compare yours to. The best way to get info/answers is to post pictures.
