I think it is 911 030 0102
I believe that the photos you posted were at the Course de côte d'Urcy 1970 where he was hill climbing another car (a 908/02), but maybe he was driving it as a factory "loan car" at the time
After being a factory car at the 1970 Swedish (KAK) rallye for Bjorn Waldegard, (car #2) it was used in France. I have a photo of Larousse with it (I think) at Circuit Paul Armagnac, Nogaro 30 March 1970, but I cant find any entry or race data. There was a Formula 3 race there that day which probably was the headline event. I thought at that time that Meznarie may have owned it but he told me (before he passed) that he didn't
After that Chasseuil and Baron had it as the #30 car at the 1971 Monte Carlo entered by "ASA racing team CIBIE" but I dont know who that was and if it had any connection to the USA ASA racing organisation
