This is an original antique (19th century) leather hunting bag and powder horn, with original accessories and contents, as of its last usage. The “honey comb” wooden cap on the powder horn indicates a Southern, most likely North Carolina, provenance.
It has a carved and decorated bone powder measure, a chain with a missing attachment, and percussion muzzleloading items inside, including a ball mold, a “nipple wrench,” and some antique containers of factory-made caps. Also there’s a pile of patch material, which would be cut up to make individual patches, used to surround each loaded roundball. Oh yes, it also has a nice little patch knife, for cutting the patches out of the raw materials, which is itself decorated with filings and an antler grip.
