Annie,
From many decades ago, when we were watching on TV old wonderful film "Les Vacances de M. Hulot" (or "Mister Ilo's Holiday" ) - that cute automobile become our favorite (for my father, my brother and me), even we didn't know too much about old-timers, and nothing about cycle-cars... Unfortunately, my father never realised his dream to have something similar... There were similar veterans in Belgrade in early sixties, at back-yards and old grages, or we could build it using some original components and some modern. Probably that I wouldn’t either succeed in that... But, some people make replica of it: my old but now gone forever friend Peter Stevenson, known better by his Cycle-Karts! Just to make you more creative pains, I will attach a few photos of his magnificent automobile!

However, I will support you in further work on project of making replica in a style of that cute Colombe/Villard replica. Just kidding, but you can always make “real” automobile: constructing four-wheel cycle-car from scratch, or reconstructing this unorthodox three-wheeler.
Ciao,
Zoran
