The picture below shows an antique full stock percussion long rifle made by the gunsmith Charles Monroe Knupp of Bakersville, Somerset County, Pennsylvania. The design of this rifle was clearly inspired by the rifles produced by his uncle Jonathan Dormayer, who was married to his aunt Barbara Knupp. The rifle is stocked in curly maple with a dark finish. The octagonal barrel appears to be significantly longer than the barrels of other rifles by Charles Monroe Knupp that I have seen.
The picture provides a complete view of the right-hand side of the rifle. The buttstock profile, patch box, wrist carving, and lock plate are clearly patterned after a typical Jonathan Dormayer rifle.
The rifle has an adjustable double set trigger setup, with a deeply curved set trigger and a subtantially straight hair trigger. The shape of the hair trigger feels different than that of the set trigger, which allows the shooter to identify which trigger is which by sense of feel. Not being conformal to the shape of the trigger finger, the hair trigger also allows better "feel" by concentrating the intentionally light trigger pull "weight" of the hair trigger on a smaller part of the finger. The projecting trigger adjustment screw can be seen between the two triggers.
