Built in 1959 and still current in 2021. At the time registrations were issued in strict alphabetical order and never re-used. This one is chronologically from 1948 and was first issued to Anson Mk.1 MG829, cancelled in 1952. The explanation is the letters match the Turbulent owner's initials: John Christopher Paul. He must have had some Pull! [To find the Anson you have to type AJCPX.]
