A further note concerning my question. The hubs I'm referring to are like the ones Nick mentions below (I happen to only have a front laced into a wheel). I looked through all the Campy catalogues and they are always referred to as Nuovo Tipo, from their first appearance in the 1967 catalogue to the 1984 catalogue, and always shown with the round holes right from 1967 on.
As of the 1973 catalogue when Campy starts assembling a Gran Sport group, these hubs are included as a component in the group, but are still always called Nuovo Tipo. As a set they are numbered 1253, as individual hubs they are numbered 1266 for the front and 1267 for the rear. But again all of the images are always the round holed flanges.
I suspect that these are not early (otherwise all the illustrations from the beginning would have likely had these racetrack holes like the Record hubs), nor are they late (given that they have 1970 locknuts). I'd like to know if perhaps they were somehow done as an experiment, for a customer, or as a mistake(?).
I wonder how many there are?
