Jeff, I believe Dan made the swivel breech action and almost everything else except the barrels and, perhaps, the cast trigger guard. I know he had to cobble together the buttplate using a couple of commercial castings and silver solder. There aren't many contemporary makers who are capable of doing what he has done. This is the first posting of the rifle that I have seen, and I hope Dan will give us a more complete description and some more pictures when he has the time. The project has been "in process" for a couple of years or more during which he has completed a few other guns, moved his home and shop and worked on restoring a military vehicle. He is a busy man.
