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

History

The car is a 1929 Tipo 8A with a Castagna body. The Turin museum says its car was used in the 1950 film Sunset Boulevard.

Coachbuild.com describes a Castagna transformable, chassis 1587, that was used in the film and later offered for sale privately.

The cached sources describe the film car's body in different ways: a coupe de ville in the museum account, a transformable on coachbuild.com, and a town car landaulet in Forbes. The museum car and chassis 1587 may not be the same car.
