The Horse Hoof was popular meerschaum motif. This one looks to be a nose warmer. It was much used and its size must have made it easy to hold in the mouth. Not something usually done with amber stems, but note how much this bit has been “chewed”. I am surprised I do not find more of these pipes in my area, which is heavy into the horse industry.
