This one came in the same lot as the Standard Modell that I posted in the Weimar section. It appears to be all matching, but someone just had to modify the bolt. I can't actually ID the Sn on the bolt root, but with all other bolt parts matching, including the extractor, I gotta believe the bolt body did as well,,,before it was "improved. Edit: just noticed FP is not matching
The Sn inside the hand guard is faint, but it is present. I can't really make out a SN in the barrel channel, but the one on the stock exterior is clear and looks good to me.
