Antique KY long rifle
Just inherited an old KY long rifle. The gunmaker has his name stamped on top of barrel. Last name is Gumpf, which I understand was a family of gunsmiths in Lancaster, PA area is late 1700's thru late 1800's. There is a first initial which looks like an L or J. Lettering is in some type of old script so not sure of first initial. Trying to ascertain the exact gunsmith so I can ballpark the age. Gun is worn and wallhanger only. It has percussion ignition and smooth bore barrel.
