Research to date on this March shows that it was raced by Carlo Franchi, “Gimax” from 1976 through 1977. Franchi entered his races under the name “Gimax”, which was a combination of his children’s names, Gigi, and Massimo (Max). Gimax was very successful with the March, winning, and finishing on the podium, many times both in non-championship, and championship, races including the Campionato Italiano de Groupo 6.
