I picked up an old hunting horn today at an estate sale, its blowing horn for calling the hounds. I believe it is really old, it has a few worm holes, a lot of patina (or dirt) and shows a lot of scraping and shaping marks. It's about 14 inches long, 3 inches across the back and has a nice double curve to lay on your side.
I don't know what I will do yet but it would make a nice primitive powder horn. The spout would need very little work, shorten it a little at the back and fit a plug and secure with wood pegs. I could make a staple and of course leave the original patina.
I used to find a few horns around and the local slaughter house would keep a box full for guys to make horns but the owner passed away and that stopped. People now seem to think they are gold plated and or were all carried by Daniel Boone but I still pick up one occasionally.
