By no means do I speak with the authority of many other students of Upper Susquehanna guns, but having edited the ALR Library book on Upper Susquehanna makers, I feel confident in saying that without a barrel signature or other very distinctive features, attributing a maker of a Upper Susquehanna gun, is hazardous , at least in this case. Perhaps, the best one can say is it is "consistent with the work of Joe Long." Check the "book" as the whole school of makers produced remarkably similar guns.
