I would not have thought that was the same car, but you could be right as both were driven by the same team and seem to have references to chassis number 001. It was (they were?) driven by Carlo Pietromarchi and Maurizio Micangeli in Group5 back in the late 1970's in many races. Perhaps you would have luck if you contact the person who took this photo: Umberto Cattani (umbcat-AT-tin.it)
