Medieval-style sword. Good old blade. Viollet-le-Duc period?

At first glance, you might think, "Well, this looks like a medieval sword."
Looking through the documentation, it doesn't exactly match any model from this period.
The blade, however, is a good old blade (still very sharp), as used on strong swords in the 17th and 18th centuries.
It is therefore likely a remounting of a good blade, on a re-creation from the second half of the 19th century, which is not uninteresting from a collection point of view.
Total length 102 cm, including a blade length of 88 cm. Blade and guard heavily oxidized. Without scabbard. Uncommon.
Approximately 4,000 medieval swords have survived. The probability of finding an authentic one is very low... In the meantime...
