Thanks guys, some very nice compliments on the rifle. Kermit , the original is an iron mounted gun. In it's current state the box lid is missing and the forend is broken away from the entry forward, but the original guard, buttplate and sideplate are wrought iron. I felt it was probably safe to assume that the ramrod pipes and muzzle cap (if there had been a muzzle cap) would have also been iron.
Ken dang it why do you always have to be so picky about the details on these things? I still have the gun here until Friday, I suppose I can go shovel the snow off the forge, get a fire going and make the neccessary adjustments...
