I have a percussion double barreled shotgun built between 1929 and 1931, the Spanish proof marks on the barrel, built by <AMR>. I have hunted with it and found it to be a blast, you talk about injecting life back into the hunt. I have also monitored some of the auctions for these doubles noting a particular strange one!! There's a George H. Daw on Gunbroker. The strange thing is that the bidding gets up there and the owner doesn't sell. Then its back on there again. This Daw has been beautifully refinished!!! Also on Gunbroker is a Thomas Bland that has been updated with fluid steel barrels!! Good stuff if you like muzzleloaders.
