1st GEN 1963 Campagnolo Record Rear Derailleur Steel Bearing Pulleys Model 1020 Steel-plated Bronze
Campagnolo released it's first modern parallelogram derailleur in 1951, the Gran Sport. In October of 1963, Campy released it's first high end derailleur, the Record 1020 (the one you're bidding on and dreaming about!) It was the beginning of an empire! It shifted amazingly compared to the Gran Sport and everything before it, and was designed to shift the recently introduced Regina 6-speed freewheel. It had adjustable, steel bearing, toothless jockey wheels (which was a design way ahead of it's time). By 1965, Campagnolo changed to plastic jockey wheels with 9 teeth, and eventually to an 11 tooth version. In 1967, Campy released the first major redesign of this derailleur, coined the "Nuovo Record". This derailleur would last through the mid 1980's. - http://www.bikerecyclery.com/1st-gen-1963-campagnolo-record-rear-derailleur-steel-bearing-pulleys-model-1020-steel-plated-bronze - Missing cage stopping bolt which many removed to save weight.
