I thought I'd add a couple of comments to the discussion. The "Black Hawk" horns appear to all be commerative. The earliest dated one I've seen, out of the good number of them out there, is from 1838, and most are later. Since Kentucky, I believe, had more troops in the War of 1812 than any other state, I'd surmise a good number of Tansel horns saw action in that war. With most Ky era (pre-1829) horns whose original owner can be identified, the owners were generally well-to-do individuals.
The Ft. Meigs horns by Francis Tansel offer us a small series of Tansel horns with documented owners. All owners of the known horns have turned out to be officers, and all were from the same company of troops who reinlisted in September, 1813 and went on into Canada with General Harrison. Their service culminated in the Battle of Thames where Tecumseh was killed.
I think the Indiana horns, post-1829, were more generalized and probably a little more affordable by the common man. The names on horns that I've chased down seem to be normal, everyday type people, not just the well-to-do of the day. The horns probably spread across the USA just as easily as the old rifles did. I've heard of them turning up in many western states, Just a couple of years ago a Tansel powder horn and cup with Turpin family provenance were auctioned off in Florida. The cup had the initials "D.R.T." for David R. Turpin, who left IN for CA during the Gold Rush and probably took both items with him. Interestingly, Timothy Tansel is buried in the Turpin family cemetery in Hendricks Co., IN. Both families had KY roots.
The Grouseland Tansel is a decent horn, purchased by the Foundation years ago, probably from Bill Guthman since he had adertised the horn for sale at one time. It has since suffered a number of "bug" bites from lack of proper care at Vincennese, and I think I got them to put moth balls inside it to slow any further deterioration. It's a little bigger than the average Tansel of that day, but otherwise the same general figures, with a mounted figure labeled "General W. H. Harrison" on the horn.... the reason for Grouseland purchasing it. Again, it's a later horn, dated 1840. All such horns had to be commerative in nature, since no Tansel accompanied the troops that marched from Indiana to Illinois.
One of my frustrations with Tansel horns is the extremely limited number of horns that survive with their original bags. I can only think of three sets I've seen that I am sure are original, i.e. not "married up, and they are all Indiana era horn & bags. Two of the three bags have some nice tooling on them, much better than average, in keeping with the horn's quality. But I have never seen an original bag & horn set from Kentucky. I used to think cups were the hardest Tansel item to locate, but now I believe it is a horn & bag set from Kentucky. Shelby Gallien
