There is no other way to account for this, plus the cock, pan, and (frizzen)having no rust/pitting, Plus the frizzen having absolutely No wear, than that this pistols re-converted.
I am not trying to find fault, but this is as it is.
I would advise putting this pistol up on another antique arms forum, and see what they say.
