Need help ID'ing Luger holster??

[Brad]

Picked up a Brown Luger holster recently. Only markings are:
A no. 18 on the back, over the letters HK 0 and under that MUNCHEN
Inside there is a large ink stamp in black BAXI

Any help in identifying this would be appreciated? Military or civilian? Approx age? etc.
Thanks
