John, the rod has about 5" missing off the larger end.
The rifle was built in Wabash, IN and the builder was listed in the 1850 and 1860 census (censi?) in Wabash County. The gent who had it in his family since the Civil War said that rod was always with the gun, the bore was plugged, and the tumbler was broken off, for all of his life and he's in his 70's. He basically thought it was junk and consigned it to an auction.
Since I feel it was original to the gun, or an ancient replacement, I would like to attempt to duplicate it with it's freestyle stripe. Heck, it could even be a gain twist.
Firelock, I might have met your father, I hung out at Doc White's from the time I was about 14 until he and his wife retired and moved to Union City Tennessee in about 1979. They later moved on to Fla. Doc had some nice books, but money was tight for me when he moved on. I'd love to have access to some of them again.
