Buck,I see a paragraph on him page 131 Gunsmiths of Maryland. I do not have Maryland Longrifles. You are right says he worked at Harpers Ferry. Thanks for pointing that out to me. On page 14 of Long rifles of Virginia ,page 154 of Virginia Gunsmiths and Allied Professions,173 of Gunsmiths of Pen-Mar-VA 1790-1840, page 87 & 88 of Gunsmiths of Virginia, and page 62 & 64 of West Virginia Gunsmiths there pictures of some of his rifles. The one in Bowers book & page 87 of Gunsmiths of Virginia are relief carved,think it is the same one.I also think the one just added to ALR Library is pictured on page 64 in Gunsmiths of West Virginia.There is also one pictured in West Virginia History Volume XLV 1984, an flintlock with an Acorn patchbox. A few months back I went to an auction in Harrisonburg VA, where an percussion signed W. Britton was. It was good cond, but plain with a Acorn Finial Hampshire County Patchbox. I got outbid.. By the way at least 40 gunmakers worked in Hampshire County.
