Might I add one more headache to the Musket, Minne musket, Rifle, or musketoon, Withney made a smooth bore, which the 1927 Dixi catalog called a musketoon, 69 cal. a real canon, I have one identical to it, except it is a 58 cal. It is a Beretta made in Belgum, markings a small anchor stamp, has Ohio stamped on stock & inlaid shield, shield missing, probely a navy arm. (canonball) Ken.
