It is about 10 ½” around the outside curve. The Cherry base is about 2”, hollowed out and is held by the same 4 steel pins that secure the base band. The tip is Whitetail antler and is a two, part pinned together with 4 pins. It is pinned to the horn with 4 more. The center band has 3 pins holding it in place. Color is AF and Brown shoe polish.
It is after the top horn on page 39 of Grant’s
Powder Horns and Their Architecture.
Although it looks to me like that horn had more than one band.
