Sometimes useful information can be obtained by contacting the local museum http://www.somerset.gov.uk/irj/public/se...95-b61e3531c2f7 which, in this case, is situated at Taunton Castle. The e-mail address is in the top right of the page. I once had a similar problem with an old muzzle loader from Essex and contact with the museum there yielded a load of stuff and also found that one of the curators there was a direct decendent of the Gunmaker I was trying to trace. Worth a try. Lagopus.....
