It is 10” tip to tip, at the center they are about 2 ½”. The center piece is hollow so the powder can flow between them. The band is fitted to cover the seam. Eight pins hold the two horns and the band. The tips are two part Whitetail antler, pinned together with three steel pins and to the horns with three more, the rear tip is solid. Each of the bands has three pins securing them.
It is the center set in the bottom pic . The bottom set of horns, although a pair, do will work for a double horn, they are to straight.
As always comments pro or con are welcome.
