In Le Cycliste 10/1950, an ad by Campy for the "Salon du Cycle", where they mention their "famous specialties: gear changers without tension on the chain, automatic and instantaneous locking of the wheels (quick release), extra-light hubs in steel and aluminum."
The bottom says: "Campagnolo, Vicenza (Italie), Cognin (France)"
Anyhow, when did Campy hubs first become _available_?
