For 1969, Chiti and his men started with a clean sheet and developed the 33/3, which featured a full monocoque chassis an a full three-liter version of the V8. Many of the privateers continued to race the 1968-vintage 33/2s for several more seasons all around the world.

Sweeping the two-liter class podium was the crowning achievement for the first generation Alfa Romeo 33 prototype racers. The name would be applied to several further evolutions, culminating in the flat-12 engine variant that clinched the 1975 World Championship. Today these early mid-engine Alfa Romeo prototypes are highly sought after and most of the survivors are part of prominent collections.

The car that will be sold by RM is of the Autodelta works cars, the 33/2 Daytona driven to victory in the 1968 Imola 500 km by Teodoro Zeccoli and Nino Vaccarella. For the 1969 season, it was sold to Antonio Zadra, who raced the V8-powered Alfa Romeo extensively but with little success. In 1970 Hubert Ascher acquired the car and he entered it for Austrian Klaus Reisch in several more events until it was retired from contemporary racing halfway through 1971.

The current owner acquired the 33/2 in 2006 and has since brought it to such prominent events as the 2009 and 2010 editions of the Goodwood Festival of Speed. He has now decided to part with the car and it will be offered at RM Auctions' 2012 Monaco sale in May.
