Whatever it is, it's still interesting.
To me, the pommel almost looks like a fleur-de-lis design. It's the crossguard that I find interesting. I don't think I've ever seen one of that period swept so far downward and in that fashion. But then, I'm more of an armor guy than a sword guy. Plus, we don't know how much of the guard is hidden under that little scabbard flap (I'm sure it has a name); it might not sweep down as far as it appears. Actually, on closer inspection, it looks like it's a continuation of a flower motif. A custom design, perhaps?
But yeah, the article does say a "very un European blade" but I don't particularly see anything special about it. You can't even see the blade, even in
other pictures it doesn't seem to stick out from under the shield anywhere. It is a rather nice effigy, though.
But I guess we'll never know how much is accurate, how much is artistic style. Shame we don't have the actual sword. It was probably just a rather ornate sword as opposed to something foreign.
