10/13/20 - This is an original black widow luger magazine from WW2. The magazine has a black bakelite base and blued tube with an fxo maker stamp and two eagle/37 proofs. The tube is also P.08 stamped but it looks like there's also a post-factory "83" stamp next to this. The bakelite base is also slightly bent out of place, resulting in a small gap on the front / toe. See photos. This doesn't affect functionality, but has been priced accordingly.
