Established in 1733 by Louis XV, the Manufacture d'Armes Blanches d'Alsace, later the Manufacture de Klingenthal, was a state sword maker, intended to cut down on the number of imports from Solingen. Operated with a civilian general manager to handle supplies and payroll, most of the actual production and quality control was run by the Artillery Corps. In 1836, when the Government decided to move sword production to Chatellerault for security reasons, the firm was bought out by the Coulaux family, who were managing the plant until then. Measuring 42 1/4 inches overall, with a 36 1/2 inch slightly curved double fuller blade, decorated on each side with martial and floral themed etched panels, and stamped "crown/B" and "crown/S" on the right ricasso. Brass hilt, with a deeply engraved and cut-through scene of an American Eagle backed by a stand of flags on the guard, "(3 stars)/E.L." stamped next to the rear quillion, raised floral and laurel vine patterns, deeply cut oak leaves on the helmet pommel and a grotesque face on the rear. With a wire wrapped rayskin grip and an iron scabbard with brass fittings, marked "6" on the throat, drag and hanging rings, and decorated with finely cut oak leaves on the suspension bands.

Very fine, with mild spotting and handling marks on the blade and a fine aged patina on the brass. The scabbard shows 70% of the original blue finish, with a smooth brown and gray patina on the remainder and some light spotting.
