Here is what I have to share http://www.wnchistory.org/Exhibits/danielsmith.html

It is a 6 foot long musket, "Long Tom", owned by Colonel Daniel Smith, the ancestor listed for my SAR membership. If you visit the Smith-McDowell House in Asheville, NC, you might see it. The curators mounted near the top of an immensley high ceiling so it is hard to find.
