This is a very early British trade pistol. I would date it as late 17th century / early 18th century. It has a 3 screw banana shaped lock with an unbridled pan by T. Gregory. The Serpent sideplate is of the earliest design. The stock has had a period repair in front of lock and between the barrel tang and lock .These blend nicely. The lock mechanism works smoothly and holds on both half and full cock. A really rare and attractive pistol seldom seen for sale. From a time when America was considered the New World!
