Note that the underside of the pommel is plain. Commonly on the Ames swords, we find the bottom half of the pommel cup embellished with an acanthus leaf design.
Each side of the blade has a typically etched Ames eagle along with the word "Liberty" needle-inscribed in a banner beneath 13 stars. The 13 stars represent the 13 original colonies.
Note the star that appears on the Ames sword on the capstan nut and quillion. Note the capstan nut on the Ames model (center) screws onto the blade tang, whereas on the Widmann M1832 (right), the blade tang is peened.
This is the pommel on a Widmann General Officer's Sword.
Note the leaf design. A similar, but more ornate, design is often seen on the Ames model.
