Thank you for the replies. I had never heard of Furstnow, or the others Red mentioned. The single loop integral 'cuff' was kinda what I had in my mind. The explanation of how uncommon holsters of that era are today makes sense. You see quite a few Civil War era holsters offered, mostly in bad shape. But there were tens of thousands of those made. Oddly enough, I do have a slimjim (made for a Single Six) and had noted that it fits the K frame pretty well.
