Logan,
You may want to check the images of the "Thomas Long" rifle on p.133 in the relatively new book, "Indiana Gunmakers 1778-1900." That gun passed through several collectors' hands years ago, including mine, since we weren't sure what it was. I first thought it was a Kentucky gun since Thomas Long was born in KY and worked there before moving to Indiana, but I never was certain of the first initial... which was kind of scroll-like. While the last name was clearly "Long" in script, the first initial could have been a "G" instead of a "T" as currently identified. The rifle is walnut stocked, long barrel, iron mounted with a cast nose cap, and looks southern. Might be worth taking a look at it.
