I bought a Model 28 years ago, used but came with a S&W holster. The 28 is long gone but the holster fits my Model 686 just fine. I was wondering who made the holster? It's for a 4" stamped S&W, 21-24. A little saddle soap & it looks new. It sort of looks like a Heiser but I'm not sure. Any value to these holsters?

There is a chart posted somewhere here that has all those codes...maybe someone can post it. You holster is a Blazer sporting holster #21. The #24 means it fits 4" S&W N frames, Dan Wessons #11 etc., and High Standard Sentinel #11. S&W once owned the holster operation and it is still operating as Gould & Goodrich.

Not Heiser quality but decent holsters for the money which is not too much.
