I remember seeing those at craft fairs in both solid brass and Armetale-type 'pewter' in the early 1970s, usually attached to belts at least an inch and a half wide and often two inches wide. The leathercraft folk kept them around for the good ol' boys who didn't hold with belt buckles featuring the peace sign or marijuana leaves or something handmade-psychedelic. When you travel the country working craft fairs for a living, you have to appeal to the widest possible audience.
You could get them with a Winchester rifle logo as well. And I remember seeing one with the Ruger phoenix on it, like something off a gun box, at least twice.
