The overall style is clearly french with modifications - I'd even dare saying that there wasn't ANY refurnituring, rather only decorating.
Take a look at these. (they are results of a google search, as I'm not home, so I can't acces my own pictures) I think these look quite the same as you sword, with only small additions.
The other possibility is of course, as Tim said, that it's "simply" a copy. If that's the case, it's a VERY CLOSE copy. The only thing is that the fuller is not low as much as on the google pictures but that's not a huge thing; and of course the marks.
I hope I could help - my favourite swords are from the medieval-renaissance era, so I'm sure that there are folks out here who are far more experienced in this field.
BTW, nice sword... and nice scabbard.
