While this is true, I notice that rear, drive side dropout has the intregral bracket for the direct mounting of a derailleur in front of the axle slot, such as a Cyclo Standard or Simplex Rigidex. This derailleur style had it last gasps in the very early 1960s and I'm surprised to even see this dropout on a 1964 model (the Grand Prix des Nations was typically held in September, after the World Championships, so any bicycle with a decal celebrating Poulidor's 1963 victory, should be no earlier than a 1964 model). Both Huret and Simplex had discontinued this derailleur style by this time and Cyclo had gone out of business in 1962, so I can only assume that Mercier was using up some excess stock and that the probabilty of it being even later than 1964 would be negligible.
