Do I have an authentic Falchion?

[Abalone]

I may have acquired what could be an authentic medievel Falchion. It looks blacksmith made, and very old. Is there someone there who would be willing to comment on the attached photos and give me their opinion? I realize there are many repros and modern made knives, swords and weapons that look very close to original... but I need to ask.

This came from a private collection that also had an authentic Viking sword and 17th century armored helmet and other items from a since deceased serious European collector.

The entire length is about 34" and the blade is about 26"

I am not a professional sword collector, and my background primarily involves antique firearms.

It is very sharp, but does not look recently done... I can't see any grinding lines near the edge, but it is as sharp as I would want any blade to be. And the edge just tapers like a wedge, with a slight rounding into the edge. It weighs about 4+ pounds (approx 2kg). There are no markings that I can see other than a lot of dings and very old nicks. Very aged pitting in various parts of the blade. The grip is wood, very dark, almost polished smooth from handling it would seem.

I read somewhere that they have only found a handful of these surviving. If this proves to be authentic, then perhaps I have something rather valuable. How can I get this appraised

Thanks...
