Old Zipp 404, missing hubs

I ran into a pair of old Zipp 404’s (the ones with the yellow zipp label), but both fromt and back wheel are missing the hubs and skewers (they are spoked so they do have the central hub; not the two on the side). I was told that this pericular hub is no longer made (American Flyer?) and parts cannot be found.

I was hoping for a set of cheap aero wheels, and not have to re spoke and re hub them. Any Ideas on where I can get these skewers and hubs, so I can take them for a spin?

Thanks,

Henk
