I don't think it was made by anybody well known. The white lettering looks like a stencil done on a typewriter.

With the open end and rivets used to end the stitching it sure looks like they didn't want to spend any more time than they had too on the main seam.

I think it's a bit newer than most, I'm going to say it's a 70's-80's. Hard to judge the weight of the leather in a picture, but if you compare it to a good quality name-brand holster I think you'll find it's lighter weight leather.

But for $5, if it works for you, it's a good deal.
