The Campbell-Napier-Railton Blue Bird was a land speed record car driven by Malcolm Campbell.

After Henry Segrave's Golden Arrow, clearly a more powerful engine was required for Blue Bird, with a chassis and transmission to handle it.

Golden Arrow's innovative vertical aerodynamic stabilising fin was also used, a first for Campbell.

On his return, Campbell set off for Daytona with the new Blue Bird, concerned at American challenges to the record.

This record stood for another year, until he himself broke it with his next car, the next Rolls-Royce-engined 1933 Blue Bird.
