This beautiful, French language, catalogue dates from late 1968, describing the range for model year 1969.
Back in the 1960s, life was simple and the Capmagnolo derailleur range was:
Campagnolo Nuovo Record (1020/A). The model shown is an early-ish version with 10 toothed pulley wheels, but random (rather than lined up) dots around the logo.
Campagnolo Valentino Extra. The model shown has 9 toothed pulley wheels.
Campagnolo Sport Extra (2180). The model shown has a large allen bolt at the b-knuckle and a 9 toothed pulley wheel.
