Is this a Luger holster?

[Steinar]

Think the black holster is a luger holster, later used by the norwegian army after the war.
But I'm only guessing, just got it trough QXL (simular to eBay). So it can come from anywhere..?
The little pocket for the tool is gone and it's modified to fit the web-belt. I know an old man who used to fix saddle's to horses, so I'm going to ask him if he can fix it

On the back it is marked K.W.K 1939 and "a1564-000061" in some white digits (realy hard to read) on the back.





Lugerdoc: what is realy the function with the police type closure strap? Draw it out faster?

Ps. I realy hope this is a geniun Luger holster, even dough it is not in a very good shape..
