Unfortunately it’s not a Perazzi , but it’s pretty cool anyway . A Family friend’s husband owned it and she wanted it to go to someone who will appreciate it . It appears to be Brown Bess cut down musket , converted to Percussion from Flintlock , then converted to a sporting gun. Chequered grips , quite elaborate furniture with gold inlays on the Baker lock conversion . 29” barrel , and choke hadn’t been invented then . Someone has treated the stock to a Ronseal special in the past , so in due course it’s going to be scrapped off and oiled before it goes on the office wall !
