I have a small collection of about 20 antique powder horns. What I have noticed as I collect them is that even though the spacing around the butt of the horn for the pegs is even, many have a section where there are 2 pegs very close together. Often one of the pegs will be a nail that I'd guess was added later.
At first I just thought that it was a repair, but the more horns I buy the more of this I'm finding. Since I'm in Appalachia, I'd wager that powder horns were used later than in other parts of the country. So there still may be some validity to my theory. What's puzzling though is that I can see no obvious signs of damage when I find this oddity.
Does anyone know why this would be done? Has anyone else found this while handling old horns?
