Thanks to all, for exchanging your thoughts on this 'country' storage horn. Dick (mr. no gold), very interesting observation about the initials being carved in a mid-18thC. plain script style.
As to it's care, I intended to: a.) put chunks of moth balls inside the horn to prevent insect infestation,
b.) using Howard's Feed N Wax on the butt plug and horn body (contains bee's wax) and finally, c.) making a plug for the spout.
Q. So, as to the style/period of the carving, is there agreement, consensus or further comment, on this, among the other responders, to my post?
Q. Is my intended plan for caring for this horn okay?
That raised spot on the throat, still has me wondering about it's intended purpose. My object/intention, is to tweak as much history out of this artifact, as possible.
