Another ID, please?

[ericnels]

Greetings, all...

I recently purchased my first Luger, a 1916 DWM. It came with the holster pictured below. The only ID on the holster is a nickel-sized (about .700") circular stamp on the underside of the flap. The number 1916 is stamped inside a smaller concentric circle (about .450"). Between the circles are what seem to be radial marks.

I would appreciate your thoughts as to the provenance of my holster and whether it is worthy of restoration.

Thanks in advance!

Eric
