To complete this puzzle, this vehicle was built in the early 1990s by John Lewis, a garage mechanic based in Radstock, near Bath, in the West of England.
John Lewis also built some other 2CV-based specials, including a fantastic motorcycle/sidecar combo, with the bike using a 2CV engine, and the 'driver' controlling the machine from the passenger sidecar, as the bike rider was a plastic skeleton! This must have caused a confused looks as he sped down he road! I'll see if I can find some photos at home.
