Today's Retro Photo: Forgotten Campagnolo Derailleurs

Well, not forgotten, but certainly among the less common examples of Campagnolo design. Included in the photo are several variations of the "Valentino," named for the son of the company's founder (and current head of the company).

The "Sport" model dates from about the 1950s, and is unique among Campagnolo's rear derailleurs in that it has only one jockey pulley. You can see one of these mounted on one of Campy Only's bikes here.
