Funny thing; in the first image, where the letters are still 'solid', i do see a H and not a B.
You must have read the e-mail i sent you; why have Christie's 'invented' that J. HORTON was active 1740-1750.
It must be something else but, a family HORTON in the gun trade had an ancestor (Joshua) active in 1750.
