I have a Bucheimer holster that I picked up I don't know where.

It is a simple belt loop mount, thumb break, open bottom holster. Stamped on the back "BUCHEIMER" inside a rectangle, beneath that "PMA- 4"

Unless I missed it, I didn't see any model numbers remotely like that in the thread so far. I'm away from home at the moment, but I'm fairly certain that I would have tried my 4" K frames in it to see if they would fit without success. Perhaps a J frame?

Anyways, this thread has left me mildly curious as to what I have here. Thanks to all who can offer any insight.
