1937 Alfa Romeo 8C 2900 B Lungo Spider
- Engine
- 2.9L twin-supercharged DOHC straight-eight

Alfa Romeo 8C 2900 B chassis 412011, one of only 38 produced, was built in 1937 with a long-chassis (Lungo) configuration and delivered new with bespoke Karosseriewerk Aug Nowack cabriolet coachwork commissioned for its first owner in northern Germany — making it uniquely the only 2900 bodied in Germany from new. Its 2,905 cc twin-supercharged double-overhead-cam engine derives directly from the 1934 Tipo B (P3) racing car. After wartime obscurity, a period in American ownership, and an engine swap, the car passed through several hands before a lengthy restoration was completed in the late 2000s by the Black family with specialist assistance. It retains rare magnesium-alloy gearbox/differential housing, numerous original numbered components, and its original Nowack body, while currently wearing period-style Zagato-attributed coachwork.
