I have a C96 that I believe to be a "pre-war commercial." I am stumped about the harness. It does not have the attachments for a cleaning rod but does have two strap attachments on the back side rather than belt loops. I can find no maker's mark on the harness but the strap with it is...

I was wondering if anyone might be able to identify the makers name of this holster and what the numbered markings may mean. Please see attached.
