French Patent # 1,375,249 - Campagnolo

French Patent 1,375,249 - Campagnolo main image

The derailleur featured here is the oft-forgotten Campagnolo Sportman (with only one 's' in its name). This interesting object had an off-set pulley cage (a feature not adopted by the top-line Campagnolo Record until a year later) and logically placed adjustment screws (a feature absent from top-line Campagnolo derailleurs for many subsequent decades).

The main claim to fame for the Campagnolo Sportman might be that it inspired the Shimano Archery series - Shimano's first design of parallelogram derailleur.
