Anyone familiar with these holsters? I just picked up a very nice tan belt holster with thumb break, marked 934 21
I can't find anything about it and Strongs catalog and chart don't use those numbers, that I can see. Anybody have one of these, or familiar with their nomenclature? I thought it was for a 39, but I don't think so, snap is a half in. from snapping......
Any info appreciated, especially a source for their old model designations

I had one a long time ago (95% sure it was a Strong) for a 2" M10 RB. It was a suede lined OWB belt holster (descent enough) but when I sold the gun (a big mistake) I sold the holster with it. It was a brownish color and had a snap strap on it but since that was in the early 80's that's about all I remember about it.
