holster maker help

Unfamiliar to me. Maybe a very very early police luger holster from the teens or twenties. Maybe the rework company? I don't have an early police holster. The earliest I have seen has the twenties teardrop strap and the earliest I have in collection is a 1929 Fischer which is a typical police maker. Wish I could be of more help.


Does anyone know when the police style of luger holster was first made?
