Sounds like a cavalry blade. Cavalry swords showed up on officers in other branches of the army often, you can see it in photographs. 35 inches is a bit long for wearing on a ship, so that cord wrap probably doesn't imply naval use. There's a branch missing on the hilt which must have taken some effort, but why? I would say you have an officer's sword that was actually used by an officer on campaign but I couldn't say what army or when. That wrapping on the scabbard may prove to be the decisive clue.Blade is 35" long. Hilt/Guard go together (very tight) so no sign of rehilting at top of pommel. It's almost like a fabric and not a cord, it's aged for sure and not done recent. Looked inside the scabbard with a light and don't see anything unusual. Wonder if whoever owned it in the past did it because when you carry it by hand that's where you carry it between the 2 rings. So he added it himself professionally. 1 large fuller all the way down almost and 1 very smaller one at the top 1/3 way down ending 1/3 before the tip.
