M,
I can't see any glaring "red-flags," or anything that says outright fake. The crossguard looks to be a B-generic type and the overall condition matches throughout.
I think you just might have found something a bit out of the ordinary. If you're going to the MAX show it to Tom Wittmann,
I'm sure he'll find this one interesting, too.
Nice find ...
Best!
