I posted some pics of my Louis Smith O/U FL rifle yesterday and figured that I may as well post pics of my 2 American powder horns (I've got a few more but they are British or Canadian):
The 1st one I'm posting is a Map Horn (shows New York, New York State and has the British coat-of-arms).
The 2nd horn has lots of images (large ship with rigging, building, animals, sun, etc).
Both of these horns have been in my possession for close to 40 years.
