Giving names to Campagnolo parts of the early 90ies can be tricky business. Some parts sold in different groups were virtually identical (especially hubs, but also FDs, sometimes RDs) or would differ only by the quality of the polishing, some parts were "handed down" through the group hierarchy from one model year to another, some more than once - so last years "Croce d'Aune" could become this years Chorus and next years Athena.
