WTB: Mavic prototype wheelset or rear track hub (finders fee)

I'm looking for wheelset pictured. It's a prototype wheelset used by the US cycling team from '94 - '96 (French team may have used them too). Finders fee if you point me in the right direction of who might have them.

I'd also be interested in just the rear track hub cartridge alone. It's a bit more narrow than the production model. See pic
