Here are a couple of simple small horns, something that could have been easily made at home. The first is 8 1/2 long, the base is 2 1/4, it is of Poplar, held in by pegs and has a nail in it for a strap. The tip is scraped out to 5 sides.
The second is 7" long, the base is also Poplar, held in with pegs and is about 2", it too has a nail in it for the strap. The body is roughly scraped to 8 panels.
