I finished the powderhorn today. I waxed it with Liberon antique wax which is mostly beewax , carnaubawax and mineral spirits. The effect looks good.
The buttplug is black walnut with a simple silver dome. the dome is attached with a screw,soldered on the inside of the dome. The peg is made of ash fitted to a hollow silver ball and hand made silver jewel chain. I had originally planed to have a ring of silver "tacks" around the base of the butt plug, but they looked out of place with the rest of the silver work. So I replaced them with a silver name plate, attached with 8 silver rivets. It was hard to take good pictures of the powderhorn.Because of the large difference in contrast, the silver tended to get over exposed and lose detail.
