1930s Cambio Vittoria Margherita :- A short clip on the workings on a mid to late 1930s Vittoria Margherita ‘Giro Di Francia’ gear changer. One of the earliest variants of ‘derailleur systems’ approved for use in the Tour De france together with the Oscar Egg Osgear ‘Super Champion’ sytems. This is an improved version over the early Cambio Vittoria (which was basically a chain tension arm and shifting was done either using an object or finger to ease the chain into desired cog). This later one has the twist lever cable operated shifter fork which made the shifting easier than the 1st variant. Not scary as seems , not noisy or ‘clunky’ as perceived definitely😅
