Pic Sport-Auto, 1975. View attachment 2495414 [/QUOTE] Picture shows via Toscanini 90 in Modena. Sport Auto is still there with the sons of Aldo Silingardi sen. and Gianni Diena sen. They came from Ferrari and worked from 1963-66 at Automobili Serenissima/Sasamotors (and Garage Camellini) in Via Malmusi (down town Modena just around the corner of Assitenza Clienti). After 1966 they formed Sport Auto and moved to the former premises of Carrozzeria Gransport in via Toscanini, where - among many other projects - the Cobra Daytonas' and the first two Serenissimas' bodies were made. 1974-80 they were commissioned by the factory to build several Ferrari 312P(B) from left over parts and restore F1 cars. And serious rumor goes that Gianni Diena was an illegitimate son of Enzo Ferrari. However, they were well connected to Ferrari and the works. About building chassis and P4 drawings I have no information.
That little car is made out of Aluminum, I found it recently and am trying to get more information. It has the number 63 on the vin plate. A 12 volt electric motor. Restoration to come.

Judging by the tires it appears to be relatively low mileage. It needs to go back to the works for a proper restoration.
The 330 P3, 412P and 330 P4 cars were nothing to do with Piero Drogo or Carrozzeria Sports Cars Modena in either design or build. The bodies were designed by Mauro Forghieri and his team, including expert Casoli, and were a Ferrari factory construction.
That car is actually pictured in the Drogo book as I have seen it. It shows it sitting in the shop when it was built and gives the time period of the build I believe. I remember seeing the thread on here but had forgotten who posted it. I have the book.
