They are striking in appearance! I like it. B&W did use some exotic woods on some of their later 800 series speakers. I remember seeing pairs of them in Tiger's Eye veneer. Very beautiful. Probably is aftermarket, but notice nice touches to detail as rear plate/sticker ID badges are intact on back. As others have said if they are in good original working condition, you have scored a good find for $750.
