I just purchased a revolver that is claimed to have been used by William Watson. I have both of his books and in reading them find no mention of this revolver, a Colt Paterson, but tha's not unusual. It was found in Liverpool, England and purchesed from a family that is decended from William Watson. I don't know their name or where they live in Liverpool. Would like to know if the story could be true, as I have no way of proving it.
Other then what is found in his books, i have no information about him.
