I'm late to the party. Look at the so-called "Jacob Dubbs" pieces, the full smooth rifle and the buttstock. There are probably about 6 or 7 more of them that I've seen over the last 10 years, some plainer like this one and some decorated, but all have the same wonky architecture and all have imported furniture and locks. There was one up at a small auction up here a few years ago too, and it's rare to see something like this up here in the hinterlands. They're all the same guy, I'm convinced of it, and I think he was pretty prolific. Unfortunatly not one of them is signed. They're all about the same period, 1780s through maybe 1810, and I think the dude was working in the 'four corners' where modern Bucks/Montgomery/Lehigh/Berks all come together. At least one other, and actually I think two, have identical tang carving. It's defintiely the same guy. Wish I knew who he was. Oh and they're all smoothbores - have not personally seen a rifled bore yet although who knows maybe they were once. But to my recollection they're all oct/rd.
