This is a Fiat 8V (Otto Vu). I’m not positive on the coachwork but it is probably Zagato given the double bubble roof. I’m still learning the very complicated ecosystem of coach building, tuning and chassis manufacturing of this time period.
Driven by Carlo Fabi (I)/Aldo Pagliacci. They finished 39th.
Note the extra windshield wiper over driver position. Wire wheels, small hood scoop.
