Large Powder Horn

I picked up this horn a few weeks back.
It's a large horn measuring 16" along the outside curve and 3 1/2" across the widest point of the butt end of the horn. I added a heavy leather strap to it to carry the weight of the horn when filled with powder. I believe it can be carried right or left side.
This is would be a great size horn for someone carrying a large bore fowler or musket.
"Rangers where required to carry sixty rounds of ball and a pound of powder."
This will be available at the Kalamazoo Trade show in March.
