U.S. Model 1821 Infantry Officer's Eagle-Head-Pommel Sword, perhaps Artillery (see Peterson pg.73, item 66), generally accepted as regulation from 1821 to about 1840. According to Peterson, infantry swords were silver over brass, while artillery was gilt over brass. This is obviously gilt over brass.
Scabbards were black leather body with either silver or gilt mounts (depending on branch of service).

Fluted bone grip. Beaded guard is bent upward at about a 45 degree angle on this example but should be at a 90 degree to the blade. Etched blade is approximately 27-3/4" in length and was likely shortened. Peterson states the fuller runs to the tip of the point and these are normally ~32-1/2" in blade length, so I am quite certain it was shortened to meet the height requirements of the owner.
