830 total Springfield Model 1847 Sappers Musketoons were manufactured from 1847-1856 with a bayonet guide on the right side of the muzzle and lug on the right rear of the front barrel band. Reportedly, 228 of these were later altered to the Artillery configuration through removal of the guide and lug, making this example one of approximately 602 unaltered specimens. The front barrel band has a brass blade front sight on the upper strap and the "6/H7" marked on top of the rear strap. The barrel has "V/P/eagle head" proof marks at the breech and "1848" on the tang. The lock has the standard federal eagle and shield motif over "US" at center and "SPRING/FIELD/1847" on the tail. The buttplate has "U.S." The stock has a faint circled script inspector cartouche on the left flat. Includes a brass hilted Sappers & Miners Saber bayonet which has a 22 inch leaf shaped blade marked "AMES MFGCO/CHICOPEE/MASS" on one side, "US/ADK/1855" on the other, and inspector marks "A.D.K./R.H.K.W." and "HO" on the pommel. Also includes a 1992 Edition of "Collector's Guide to Ames U.S. Contract Military Edged Weapons: 1832-1906" by Ron G. Hickox in which these Sappers & Miners bayonets are described on pages 31-33.
