A lot of makers made that style back in the 1950s - 1960s.

I have some that are very similar, but none exact. Someone may
have the exact same holster with the writing on the back intact.

If so , they can tell you who made it.

It's worth what you paid for it, if you can use it, but not a lot more.

You can usually find them on the big auction site.

It could be a Bucheimer with those two rivets added to keep
the seam from pulling apart?
