Clint,
I have developed a small interest in those cut-down Artillery holsters used in the Weimar period.
I like the variety you see in how they are modified.
Here are 3 in my holster collection.
The one on the left is dated 1918 (on the back, as the close up shows).
The one in the middle is dated 1917 on the inside of the closure flap.
The one on the right has no markings.
I had Master Jerry Burney replace the closure straps on the middle one and the right one.
The one on the left and the one in the middle do not have any evidence of gun marks or impressions along the interior surfaces; so I suspect these original holsters were never issued and modified after WWI sometime. The one of the right has lot of use and carry history evident from wear, impressions inside, and a series of modifications.
