J.L.S.
 

I have a Imperial holster with these markings J.L.S. and no other numbers to go with it. Is this a Unit mark?
Thanks

Where on the holster is the marking? Is it inked or embossed?

Under the flap and is embossed.

Under the flap on the front of the body?

It's on the back side of the flap. The marking are the result of using a metal stamp. And the embosses is probably incorrect. If this mark is a unit mark. I think it is a Jager Landwehr/Landstrum Stosstupp. Which is cool if correct. I will post pictures later this week.

Here is a picture of the mark in question. A Walther Md4 fits perfectly in the holster. But a Walther PP which is a bit larger does not. You can get the PP in the holster but you cant close the flap strap.

Beautiful holster. I don't believe the marking to be a unit marking. Perhaps it has a connection to the manufacturer or retailer.
