This is a very nice utilitarian backsword. It is 25 1/2" long with a 19 1/2" blade which is free from any decoration. The handle is plain wood with a brass crosspiece and pommel.
I don't know anything about the origins or history of this blade, but it does have a certain military look to it. The curve and length of the blade, and the angling of the handle suggests a cavalry sword, but I don't know for sure.
