The very small oval mark with an "S" under a star directly under the hilt could perhaps be the mark of Francois Antoine Schütz. He has been controler of blades since 1853 in the armsfactory of Châtellerault. May be he was controler at Klingenthal in the years before too.
The second possibility is that the blade has been made by the armsfactory of Châtellerault and afterwards was sold to Klingenthal, where it got the signature of Klingenthal.
