This is a senior administrative officer's sword, probably either a surgeon or an apothecary, viz the twin-headed serpent on the guard. The little dolphin head at the end of the knuckle bow by the pommel indicates the naval branch of service. The mounts are ormolu and the grip is ebony.

This sword, dating from 1805-09, would have been carried by an Inspecteur aux (or 'des') Revues (the equivalent of Commissary in the British Army), responsible for pay, provisions (hence the ears of wheat on the guard and knuckle bow) and the depot system. Before this, they simply carried an ordinary infantry sword. The sword is rare.
