Hello Citlali,
While all indications are that your sword is the U.S. Model 1832 Foot Artillery sword, it is interesting that the blade does not carry the Ames Sword Co. markings (Chicopee, Mass.), the firm that carried the contract to make these swords for the U.S. government. Ames obtained the original contract in 1832 and actually produced about 20,000 of them by 1862 when production ceased.
It is known however, that like many large firms, Ames did subcontract work, particularly in the early production years, prior to thier move to Chicopee Falls, Mass. in 1834.
The eagle on your blade is characteristic of Ames M1832 blades, and the WS represents one of thier inspectors, William Smith, whose initials also appear on many of the Ames M1833 cavalry sabres (known dates c.1837).
The 1841 on your sword suggests a date, however it seems quite possible as well that with the possibility of the subcontracting, this could plausibly be a numeric for inventory purposes. Equally a date may be possible showing this sword made in that year with Mr.Smith's inspection for accounting purposes.
In either case, the early production of this sword remains plausible.
As I indicated in our discussion, these swords indeed recall the Roman gladius and were actually designed after the neoclassic French M1816 swords of this type which they 'affectionately' called 'coupe choux' (=cabbage cutter)
While typically considered unwieldy in combat, the M1832 Foot Artillery swords apparantly served well as 'choppers' in the Florida swamps during the 2nd Seminole War.
It is interesting that the similarity of these swords to the ancient Roman gladius has had occasion to cause quite a stir in the archaeological sphere, when in one case years ago one was dug up in the New York area if I recall. The attending archaeologists naively assumed they had discovered evidence of early Romans in New York !!
and were quite chagrined when a researcher 'cooled thier jets'!!
Although we dont do valuations on the forum, I will note that early U.S. items are typically very collectible, and of course this brings forward the possibility of 'reproductions'. "Man at Arms" magazine is an outstanding resource on U.S. weapons, and they would be a great contact for this type information.
All the best,
Jim
