From 1926 - 1931, Phantom Is were also built for the American market in Springfield, Massachusetts, USA. Like the Springfield Silver Ghosts that preceded them, these cars were originally the same mechanically as the English built versions, but eventually left hand drive and centre gearchange were introduced. They differed mainly by their use of American coachwork and locally sourced electrical equipment.

Similar to the Derby Phantom 1, but left hand drive.

Early Silver Ghosts and Springfield-built cars were not assigned Chassis Series as such. We have taken the liberty of creating a Chassis Series for these cars to help list and describe them. Please ask.
