RBS,
Thanks for sharing photos and information with us regarding this fine looking firearm. There is a lot to like about this gun! The only documented Upper Susquehanna region gunmaker named ROUSH/ROUSCH/RAUSCH that I could locate in my files was a David Roush b. 1799 from Freeburg, Union/Snyder Co, PA. To my eyes your gun looks to have been made a generation or so before this guy was making guns. Your gun obviously came off the bench equiped with a flintlock. Perhaps David Roush apprenticed under an uncle or older cousin "M. Roush" who has yet to be documented as a gunsmith? From the workmanship seen on your "M. Roush" gun, it's clear that this guy knew his way around a work bench and how to skillfully use the tools of the trade. Below is some of the bio information I have on David Roush. Hoping this helps to piece together the identity of the maker of your gun. Note that David Roush had an uncle named John Martin Roush/Rausch. Back then it was common for folks, especially of German heritage, to be called by their middle names. Perhaps this is our guy??? Also note that David's mother's maiden name was Morr. There were at least a couple MORR family gunsmiths in the Central PA area back then. Thanks again for your post.
