Whatisit?

[PRD1]

I've had this holster for some time - it came with a post-WW1 .30 rebuild Luger.
I've always assumed that it is commercialy made, but it is very sturdy and well made, and I'd like to know if it is actually of any known type.
Ignore the pistol - it's just one I was making photos of at the same time, and used for a weight to keep the holster flap open...


Thanks;
