Production

Every figure says what it counts.

Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.

History

The Bluebird prototype was launched at Earls Court in 1954 and used by Donald Campbell from 1954 to 1956 while it was still owned by AC Cars. During that time it received a Bristol 100B engine, which became standard for later Acecas. The car later fell into disuse and was restored; it is now displayed at the Lakeland Motor Museum.
