I have a picture of M.Poulidor taken at the 1966 Tour de France (unfortunately, it is looking at the left side of the bicycle) and the crankset is a Stronglight 49, the front derailleur is a Simplex (can't see the rear derailleur), the brakes are Mafacs, the shifters appear to be Campagnolo as do the small flange hubs!!
