1900 Commercial Holster?

[Mark1]

I've owned this holster for a while but have never seen an other one exactly like it. It came with my 1900 Commercial Luger and is similar to a P08 holster in some ways but the main points of difference are...
*from top to toe is about 10mm more than a P08 holster
*the stitching is much closer spacing than a P08
*the lifting strap and finger grip are wider
*there is a tool pouch and another loop inside the lid
*the belt loops are spaced closer together
The holster is well made and seems old but has no markings at all. Is it an early Commercial model? I would be most interested to hear any comments from the forum members.
