According to this Coachbuild.com forum, this is chassis 3AX199, “owned until 2001 by famous American actor Carroll O’Connor … Supplied originally to James Onslow Kingsmill Delap in Kenya (founder of East African Airways). It went to the UK in 1966 and from there to the USA later on … The boot could only be accessed from inside the car, to keep out the African dust.”
Thanks very much to user Phantom3 for the additional information.
