Thanks very much for the comments and views.
Now what if I said it had a Death's Head on it? The DH itself looks to be the same age as the holster to me, and the die used to stamp it was well made- JMHO.
A DH fits right in to the time frame of 1920-30s. As does the proofs on the luger that came in it.
A picture of the luger is also shown. You can also see more on the pistol at this link:

Question is why the DH on the holster ?
I can think of some possible reasons:
-Old minenwerfer vet had it made
-plain clothes detective with nefarious connections
-some important person's newly formed body guard
You can no doubt add more. Another question of origin and purpose we can likely never answer , but interesting holster for sure.
Comments and speculation welcome.
