I was looking at the powder horns at the DAR Museum that Sequatchie Rifle kindly posted and it brought up a question that I have wondered about. On original powder horns, say from 1770- 1870, what was the most commonly used material for pinning the base plug. I know that horn makers say that you can use wooden pins, brass pins iron pins, brass and iron nails and tacks, etc. But what I am asking is not for a list of all possibilities, but what turns up most often. My guess is iron nails, but that is absolutely a guess.
Can someone knowledgeable provide some illumination on this?
