Cal 45-75. Musket has a 32″ round bbl with bayonet lug and cleaning rod present. Bbl is a silver color. Appears to have been cleaned with some sort of solvent. No blue is present on the bbl. Flip up ladder sight. Inside is a rather dark bore. Rifling quite strong but is definitely in need of a good cleaning. Cleaning continues on the receiver and it is a grey color. Looks like someone attempted to refinish the side plates with limited success. Metal is smooth. Original dust cover. Stock has been redone and is somewhat shy at the tangs and has a glossy finish. Other than that, wood is in good overall condition.
