1939 Alfa Romeo 6C 2300 B Berlinetta Sport

1939 Alfa Romeo 6C 2300 B Navigation
This Alfa Romeo Berlinetta Sport is the prototype built for the 1940 Mille Miglia by Castagna. The 1940 Mille Miglia was never run and this car is the sole survivor of the 10 short chassis cars that were built by the company. It is constructed of aluminum and is in its original color scheme. Originally the car was built with the normal 2.3-liter six-cylinder engine, but this car now has one of two prototype 3.5-liter V12 engines designed by Colombo. It was installed by the owner, as planned for by Alfa Romeo, just as war halted production in 1939.
