1949 Campagnolo Paris-Roubaix Rear Derailleur, includes Campagnolo 40H Rear Hub, Regina Gran Sport Course 5 speed 14-16-18-20-22 Freewheel.  All items are new old stock. Friction shifting, pivot lever.
With a single lever, the Campagnolo Paris-Roubaix derailleur requires one to back pedal, loosen the rear quick release with a 1/8 turn, then with the same lever, shift the chain to another sprocket, then tighten the quick release.  It is beautifully designed and extremely rare. In 1950 Coppi won the Paris-Roubaix using Campagnolo’s newest derailleur the “Una leva” (single lever) model which superseded the “Due leve” (two lever Cambio Cross model). Following Coppi’s win the new mechanism was renamed the Paris-Roubaix model.
To change gear the riders would:
a) Reach back to the seat-stay mounted lever.
b) Back pedal.
c) Turn the lever releasing the rear wheel. (The lever is in effect a extended quick release)
d) The action of releasing the wheel would engage the lever with a fork mounted over the chain enabling the rider to select the sprocket he wanted by turning the lever.
e) Once the chain was engaged on the correct sprocket the rider would stop backpedaling and turn the lever back to it’s locked position. This action would lock the wheel and release the changing fork.
f) The rider could then pedal forward again and go on his merry way.
