Randy,
Great job on the swivel breech. I too share a fascination with wenders ever since laying hands on an original back in the early seventies. I've queried every gunmaker that has ever fashioned a swivel breech mechanism hoping to sop up whatever knowledge I could obtain. And then along comes Dave Waters and David Price. Where were these guys twenty or so years ago. I first met Dave Waters about five or so years ago at Dixon's Gun Makers Fair and David Price about three years ago. I settled on a David Price "kit" for lack of a better word. He'll assemble the action on the barrels or include the wood and furniture. The nice thing about his system is that if you want another set of barrels, say, a rifled barrel over smooth bore or two smooth bores, he can assemble them to the point that when you receive them they will attach right into your stock. I'm anxious to finish my rifle as I'd like to use it this fall in deer season. I'd love to meet three deer in particular that I missed over the last forty years of hunting with a flintlock. I'd have a .54 cal surprise for them after they finished watching the pretty blue smoke blow away.
