Standard pattern, m.1840, Peterson #10. Good quality example made by EMERSON & SILVER and sop marked with 1863 date to the blade base. Brass hilt modified by bending both side guards down which rendered it non conforming to the Union pattern Additionally, remnants of black paint indicate that it was used with the hilt, but for the grip, painted black. These modifications are typical and well know adaptation to Confederate use. From the famed Frank Barnyak collection. Blade with some superficial staining only and much original bright finish. Marking crisp.
