Overall lengths 55.5" to 56.625" (long version), 49.5" (short version); barrel lengths 39" to 39.125" (long version), 33" (short version); caliber .69-.72 (rifled). Markings: "Crause in Herzberg" inscribed in script on the backstrap of the hammer housing, the "s" in archaic form, appearing as an "f". Nicknamed the "Cyclops" because its large center-hung hammer is pierced with a large window that served as its rear sight. A few hundred of these clumsy rifled muskets may have been intermixed with the shipments of "Saxon" muskets imported in 1861 or 1862 into the United States during the American Civil War.
