The revolvers were made by Selby S Webb. He lived to a great age, was still making single actions into his 80s. There is some information about him on the 'net. He liked making single action revolvers; at least one single shot pistol. In 1938 he made a revolving .410 shotgun. These revolvers are handmade, do not use anyone else's parts. I did make the ejector assembly on the lower revolver - you can see I used ball point pen springs for the ejector return spring. Made a replacement locking bolt for that one, as well. They are not identical; very similar, but differing in detail. He must have made some jigs and fixtures, particularly for making the cylinders. His workshop had turning and milling capability, but much/most of the work is done by hand. The trigger guard and backstrap units are fabricated from pieces. Incidentally, these pre-date the Ruger single action .22s.
The auto I know less about. As far as I can tell, it is an original design, not a copy of anything else. Accompanied by a handmade holster. With standard velocity LRs, it shoots very smoothly.
