This is a pistol like the one he has. The one in the picture is in pristine condition compared to his. It is a .41 caliber smooth bore. I told him I would take it home and clean it up for him but he said no. ? . He knows nothing about muzzle loaders and even less about cleaning one up and getting the rust out of the bore and off of the outside of the pistol. Oh well... Does anyone know anything about the .41 caliber Mendi derringer? He got some .36 caliber round balls with it but that didn't seem right. They would have to be too small, right?
