Well, I was running down the Maserati line, as I thought the nose was familiar, when I discovered the offshoot company Officine Specializzate Costruzioni Automobili. This was formed when Ernesto and his two brothers Ettore, and Bindo Maserati left Maserati after their contract expired following their sale of shares in Maserati.
The pictured car is, I hope, a 1947 O.S.C.A. MT4 and it won the Napoli GP.
Phew, that took long enough to find...
If correct can we have a black please.
