phdm is the answer,

What Gérard Pillon had told me is that he had 3 Brabhams: one F3, one F2 and one IC.
He did not remember what model the F2 was. He did mention chassis n° 5 but I would be rather skeptical about this number for the reasons explained above.
For what it is worth, he said he had bought the car in 1969 from Habegger who had been Swiss champion with it in 1968. He had seen the car at Ollon-Villars. He did not keep it for long (how long ?).
