Mystery freehub

Chasingabee

I've acquired some Mavic wheels, believing them to have a campagnolo compatible freehub. However, on closer inspection, the freehub spline pattern doesn't match anything I can find in the internet. There are 6 splines, unevenly shaped and spaced.

Any ideas as to what they fit?

I'd need to see a better photo, but that seems to be a third party hub that would take a Campagnolo cassette with some of the cassette slots not being used.
