Hi,
Somebody tried to copy a Pedersoli Bess. The lock plate engraving seems to give it away. It looks like the Pedersoli, even has the incorrect Grice 1762, but it is different. The crown is different and so is the lettering. The maker added the crown arrows but forgot to cap them with little crowns. Same thing on the barrel tang. He did a fine job on the inletting and finish. It is unfortunate that he copied a Pedersoli rather than a real pattern 1769 Bess. I have no idea about the barrel. It looks far better than those on India-made stuff but the letter soup is a mystery to me.
