Chassis 14397 is a right-hand drive 1971 Ferrari 365 GTB/4 Berlinetta that was converted to Spyder configuration in 1978 by CP Autokraft, with body dimensions taken from a genuine factory Spyder. Delivered new in the UK to its first owner via Maranello Concessionaires, the car passed through several notable British owners before spending time in Australia, and returned to the UK in 2013. Repainted to its original red with black leather, it is regarded as among the best-known Daytona conversions in Britain.
