The car is a Fiat 600 T multipla based that took part in the carovane of Tour the France 1961, together with two Renault bodied by Pourtout; this Fiat, anyway, has certainly not been bodied by the French coachbuilder.
As five of these care took part in '65 Tour with Esso or Total (I don't remember) sponsor, and they were called the "Boneschi Circus", I suppone this car is a Fiat 600 T Multipla Boneschi, from 1961 (probably a 600 D, with 767 cc. engine).
