I'm trying to get the Crepaldi-Bianco-Italfrance-Autocorse-Gilco-Colli-Allemano-Panhard connection right.
So far I understood:
1- Crepaldi was not a Carrozzeria but an importer of French cars (and later a Ferrari dealer) and founder of the Scuderia Italfrance, were Panhard-based cars were used to race. Those Panhards were built by Aldo 'Tino' Bianchi and bodied by Allemano. In 1952 Crepaldi left Italfrance. Colli bodied some Panhard later and Bianchi was always the builder. He later opened a workshop called Autocorse and Colli bodied a Panhard for it too.
It seems that this one is not one of those cars!
In 1954 Adriano Zerbini drove a Panhard Barchetta built in Bologna by Carrozzeria Fratelli Rimondi at the Mille Miglia, Raticosa, Firenze-Siena, Bologna-San Luca and in a race in Bologna (Campionato dell'AC Bologna). The car had a small circular grille on the front and license #BO65701.
That car (same license number) was drove by Zerbini at the 1956 Mille Miglia in the configuration shown above, the puzzle car.
