the postman brought this one today. It is from Selzig Saddlery of Houston, Texas, a bit unusual in that it is for a 4 inch N frame. The majority of the vintage revolver holsters I run on to are K frame or for Colt DAs.
Some old holsters have no markings, some have a lot.
The GPD, Quien Sabe Galveston, Gladewater, Gilmer? 3844 for $4.50 back then.
