The last ones listed look like( very much so )Walther PP holsters (one is post war last one)........Check every part of each holster to look for markings........inside side under the flap......The end to the strap (outer part) even with a magnifying glass ......back of holster. Because of the number of holsters, Also the stud, I will check your holsters a little at a time.
