4/24/20 - This is a super rare, highly collectible, and early nazi era Walther PP holster. The holster is NSFK stamped on the front, which was a predecessor of the Luftwaffe (basically the German air force when the Germans weren't allowed to have an air force). The holster is stamped on the front leather with the NSFK logo and a banner "N.S.F.K." above the flying man's head. This stamp is fairly faint but definitely distinguishable. There's also some light surface cracking on the top leather (I think the photos make this look worse, but please look at the photos!) The holster is also maker stamped by AKAH under the closure strap, and Walther PP ink stamped on the interior leather. The stitching is all original and in tact.
