OK, OK, I give, I will give the horn a slight patina.
Dave B. The collar is not applied, it is integral to the horn. As for the copper band attachment, because the raw horn needed to start out some what thick to panel it I was able to attach the base of the horn to a tapered wood plug in my lathe and reduce the area for the band which created a forward shoulder for the band to butt up against. Doing this allowed me to install the band from the base end of the horn and "capture" it between the shoulder and the base plug. The square pegs in the copper band are shoe pegs. I learned about using them from Mike Small, another great horner. As for the inspiration for the horn you need only turn to page 36 of Madison Grant's book, Powder Horns and their Architecture.
Thanks for all the compliments. I am working on rigging the rest of the bag, bullet board, powder measure, brush and pick etc.
