230.1-1 The Sappers musketoon is generally similar to the artillery musketoon but it has lugs on the right side of the barrel and upper barrel band for its Roman-pattern sword bayonet. Model 1847 Sappers Musketoon  230. Service Configuration 230.1 The sappers musketoon was the first of the three musketoons adopted in 1847 to be produced in quantity. The first order for 200 of the musketoon’s special, Roman-pattern bayonet was given to the N. P. Ames Company on December 21, 1846. The blades of these sword bayonets had fullers, or grooves, in the sides. A second order, for 300 bayonets, given to the Ames company on February 19, 1847, stated “The grooves in the blades to be left out.” All of the musketoons produced at Springfield Armory during the first half of 1847 were sappers musketoons. It should be noted that sappers musketoons were fabricated at Springfield Armory in two distinct periods; they were still in production when the Model 1855 series of arms was adopted. An order for 500 sappers musketoon bayonets was given to N. P. Ames on February 1, 1855. Colonel Craig ordered Captain R. H. K. Whitely to inspect the completed bayonets on May 18. The final order to Ames, on November 27, was for 33 sappers musketoon bayonets. On July 6, 1855, Chief of Ordnance Colonel Craig wrote to Springfield Armory Superintendent James S. Whitney regarding the new arms that had been adopted, and gave instructions regarding the arms already in service. He stated “The Sappers Musketoon [is] to be dispensed with.” General Information Caliber: .69 smooth-bored Overall Length: 411 /16" Finish: All metal parts are finished “National Armory Bright,” except for the internal lock parts, trigger, the bow’s slotted nuts, and screws, which are heat blued from the drawing process.

The rear profile inclines slightly rearward and terminates in the flash shield at the top. The flat outer surface is flush with the lockplate’s surface. Bayonet Lug: There are two components to the bayonet support and locking system. The rear support lug is located at the rear barrel ring of the upper band and is described with the band. There is also a 7 /8" by 3 /16" locking and support key on the right side of the barrel, 1 /4" from the muzzle. The bayonet ’s locking ring engages a 5 /16"-long rectangular mortise in the center of this key, to secure the bayonet. Breech Plug Tang: The 2" by 9 /16" tang is round-ended. Muzzle Extension: 27 /8" Other: A 3 /16" by 1 /4" rectangular stud on top of the barrel 51 /8" from the muzzle prevents the upper band from rotating when the bayonet is attached.
