I've got a very very tidy set of black bulb hubs. I need to check but may have some nos Mavic rims, can't remember if they are 729s or 819s or something like that.
Which type are you after? There are three versions of Bulbs;
Mk1 - 5 bolt via a removable spider
Mk2 - 6 bolt with disc tabs going all the way to the flange
Mk3 - 6 bolt with truncated disc tabs, sealed at the inner end (as opposed to the Pro II which was open)
