I have an original bag and horn from Hardy County, WVA. No idea how old it is. The horn is very plain. The butt was not shaped, the plug was whittled to fit instead. It has a large iron staple in the plug and a previous owners initials carved (crudely) in the plug. The horn is attached to the bag straps with leather straps.
If you like, I can try to take some pictures this weekend and email them to you. No promises, I have a wedding on Saturday and may not get to it.
