Old saber from a barn in northeastern Pennsylvania

[Lee]

Ulfberth, I think that you have surely 'nailed' it right on the head! The owner remembers swinging it around in the barn as a child. I'll ask if there is anything in the family history that might favor any of the possibilities pointed out by M. Eley. I know that my friend also has what he believes is an American Civil War naval officer's sword along with a picture of the original owner in uniform wearing it! I'll see about getting pictures of that and will report back whatever else I learn.

The flat back did make me wonder if the blade were French, but there were no remains of any engraving there. So, I do not feel totally ignorant and my friend will be thrilled that with your help the original origin has been identified. Thank you all for your assistance thus far!
