Tom,
Check your e-mail. What an absolutely stunning dagger and to find a pair.........just wow. Certainly a WKC produced cross-guard in my opinion, the WKC 1st and 2nd ( transitional ) also show the same five sections of segments on either wing, nearly all other makers only show four distinct sections with the exception of Klass and some early Paul Weyersburgs.
Including this one and your other, I have now seen five in total. That should answer your question on the rarity .
