5/19/20 - This holster came with an early Walther PP, which would be correct for an NSFK holster. The NSFK was the Flight Corp, or early Luftwaffe.
The NSFK holster is very rare, but we have ONLY ever seen them as specially-made AKAH holsters worth about $4500. This holster is not Akah nor is it the correct style. So that is a strong caution on this holster. However, it does have a correct looking NSFK Nazi Eagle insignia on the front flap. If you want to take a chance it is a very nice looking holster for a Walther PP or PPK. There are light scuffs on the holster throughout. There is light cracking in the seam of the top flap. The NSFK marking is faint but visible.
