Navy Luger Rig Attachment

I have a CMR Navy rig reproduction and I was wondering how to attach the holster to a belt. Someone on the old forum said to check a book, Imperial Navy Lugers I think, which I don't have. What I really would like is a picture of what goes where. Here's my Luger and the CMR holster:
Obviously I'm not going to be using a stock on this one but I'm curious if it is configurable for use without a stock attaching to a belt. Any info would be helpful. Thanks.
