1950's (maybe 1955) design by Philippe Charbonneaux on a Cirtroen 2CV chassis. Built by Pacaud.
Its amazing what designers back then did to "mundane" cars like the 2CV.
2CV designed by Charbonneaux is right, but I have a different builder..
Locked for you to see if you can match what I have (which I hope is right...) or prove I'm wrong!
Although you're an Expert now so can't answer Rookie puzzles any more I'll let you have this one since you've got most of the answer already..
If you find you can't post in this thread let me know by PM and I'll move it to the Experts to enable you to answer.
