Seems like this was at one point a fairly popular holster. I found the Don Hume H702 listed on ebay. They made it for revolvers with 2" and 4" barrels for the J, K, L, and N frame revolvers. Most had a retention strap attached with snaps on both ends making it removable. Being a revolver fan I think I will attempt making on for my .357. Thanks again for sharing the inspiration for your holster, Josh.
