At the risk of missing the mark entirely without first consulting my meager reference library, the grip scale inserts and fleur de lis on the cross guard both have a distinctively French feel IMHO.
Does the capstan (rivet) unscrew from the pommel? The image of the knight on the scabbard gives the sword a fraternal feel, though the general sword pattern somewhat resembles court swords or diplomatic swords of the Victorian era.
I'm sure someone else will be able to contribute something more definitive than my best-guess efforts...
