I have been told that this is a Cadet Officer's Sword from the Civil War Era; only recently have I been able to confirm this. I have owned two of these and do not possess one at this time.
The sword is based upon French (ultimately U.S.) patterns of the 1840 era, namely the 1840 NCO and 1840 Musician's swords. The hilt is of solid brass and the "simulated wire-wrap" is integral to the silver plated grip; again, both of my samples lacked plating; why, I do not know.
There are quite a lot of Cadet Sword variations; many, if not most, were privately purchased.
Most of these are devoid of markings, other than perhaps MA    (for "Military Academy").

West Point Cadet Name Searches

I have various information on West Point Cadets - graduates and non-graduates - from 1802 to 2002. If there is a name on your sword - and that name is registered as a West Point Cadet - I can very likely supply basic information on that individual. I charge $10 to search, non-refundable. If a record is found, I will forward that information on to you via e-mail; if no record is found, I will e-mail you to that effect. Follow this link to request a West Point Cadet Search.
