8/15/19 - This is a WW2 style FN model 1922 / Femaru M37 holster. The holster is luftwaffe stamped on the interior leather, as well as ink stamped with a pistol designation, but the ink stamp is too faded and faint to determine which is designated. The luftwaffe eagle is underneath this ink stamp, and is hard to see in photos but evident on the interior leather. There are no other markings. The black leather has normal wear / pliability and someone modified the closure strap by cutting a slit in it to make it larger - see photos. All original stitching in tact.
