Almost the spitting image of the one in the above post but half stock, half octagon barrel, also with set triggers. Used to shoot it until the nipple blew out of the bolster and put a divot in my forehead. Bought in 1979, since retired.
Barrel is marked Wilhelm serial #128 Got it at Greentop just north of Richmond, paid $125. 11 lands of rifling, flint converted to percussion.
