Can anyone ID this holster? It is a western style double loop design but it has a finish much like some foreign military leather goods. Also has a drain hole. I believe the retention strap and snap are a later add on. The previous owner said a large frame DA would fit and if I measure from the cylinder impression it will take up to a 5" barrel, maybe only a 4 3/4" barrel. No markings or stamps anywhere on it. Thanks for the help.
