Oh yeah, Bill, I'm with you. There was just something about the stock architecture that works at me too. I finally found the picture of why it's so familiar, hadn't seen it for several years. It's from the older "Men-At-Arms" series by Osprey, "The Jacobite Rebellions: 1689-1745". The illustration is of, "The Laird of Grant's Champion, Alastair Grant Mor, 1714" by Richard Waitt. The painting, now the property of the Earl of Seafield, shows Mor in a fighting position with the gun leaned against the wall behind him. The photo is rather dark and I have no way to scan it in now. Because the lock side is turned away from prospective, there's no way to tell if it's of a similar ignition as this gun but probability is high. As remarkable as the gun itself is Mor's raised broadsword with it's curved blade. Both sword and gun were firsts for me.
