IMHO, based solely on the photographs that have been displayed, I believe the gun, and all stock fittings are original, and
PROBABLY falls within the ATFE C&R definition that has been mentioned previously. BUT, the stock and the forearm
appear to be reproductions.
The checkering on the stock and forearm does not seem to ME to be up to factory standards. Still, all in all, it is a fine looking Luger and would certainly display well on MY wall.
