Enjoyed the pics and the write up. Thank you.
I may be entirely off track, but I can't help but wonder if this was originally intended as a salt horn or other container of some sort and then used as a powder horn? I look at the horn and wonder how tight the butt plug was originally. The reason I ask is because of the leather strap on the butt end seems to suggest it may be for easy and/or frequent filling. Of course, it may also have been for frequent emptying to dry out damp powder.
