I grew up in Hopewell (NJ) and my third grade teacher's husband (Jack Dotson, iirc) was a collector of kentuckies. He had donated a Reading rifle and I think a couple of other pieces to the little Hopewell museum, and I spoke to him on the phone once when I was in my late teens/early 20s. He did have a couple of rifles that he said were made somewhere around the central NJ area ca. 1800 give or take a bit (again iirc) and he had some information on the makers, but we moved away and I didn't get a chance to get back there until after he had died. I don't know what happened to his collection but I always heard he had a pretty huge pile of "stuff."
