This sword is made of, I think, two different types of metal. It is 24.5 inches long (from tip to the bottom of the hilt) and the hilt is about 4 inches across (pictured). It has a sheath that appears to be leather and it has the engraving of an eagle on a branch at the base of the handle. It also has a few things stamped into the metal. At the base of the blade on one side it says "US 1855" and on the other side it says--I can't make out all the letters, but something like "AMES M_CGG CHICOPEE". It also has two sets of initials carved into the hilt; one that says "A.D.K." and another below it, slightly larger and in cursive, that says "RHKW."

My uncle was an antique gun collector and he also collected a few swords and other militaria as well. He left me this and a few other items when he passed away.
