This belongs to a friend of mine. The only picture I have at the moment. Cap lock but looks like it might have been converted from a flintlock. 45 caliber. It is a full stock, long barrel, with a trigger and set trigger. No patch box. The stock does have a cheek piece and a butt plate. He believes it to have been handed down for numerous generations. The letters "AB" are on the top flat of the barrel which he says are the initials of a grandfather or great grand father or great great grandfather.
