At first glance I would say 18th c., made "a l'ancienne" / "a la antigua" to fit a smallsword/court sword/military sword hilt; probably in Solingen. Either that, or a refitted 17th c. blade, but that's less probable for what (relatively) little can be seen in these pics.
All of this just in theory, of course. There's a lot of things I would like to see from up close before passing a judgement for real, not the least of them the tang, or a better picture of the forte with the inscription.
Not to mention the condition of both blade and scabbard is extremely good. Nothing that should make us jump to any precipitate conclusion, surely, but worth considering with caution, nonetheless, in a sad world like ours...
