Oh, I've missed that one !
I can give you a bit more accurate details, as I know quite well Bernard Delsaux, we've already met four or five times.
In fact, I have the project to write a quite big and detailed article in the "Retro" column of Generation Sans Permis, as soon as Mr. Delsaux will have find a bit more period pictures...
Anyway, in fact Delsaux started his voiturette business quite a bit before : he delivered his very first 3-wheelers already in 1976, after having worked a bit on the very first Erad Capucine !
Voiturette business is a very small world in France
Still, nobody seems to know that. Even l'Auto Journal didn't gave any mention of Delsaux before 1979, but it is quite logical. As with a few others very small voiturette companies, Delsaux started without showing his first cars at the Paris Motorshow or any "big" national event.
In most of the cases, René Bellu got to know the new faces of the voiturette market just be going to the motorbike or car parisian show, but some very obscure brands had never appeared at the Porte de Versailles.
Same thing for the 4-wheeler : the type-40 Modulo was already on sale in 1979. Still, Delsaux never produced more than 200 cars per year, as he always had less than ten employees.
Lately, he tried to increase a bit the Modulo sales with the Minimax (new body, numerous mechanicals tweaks), but on a cut-throat french voiturette market, it was already too late.
He stopped for good in may 1984, to become the last sales director at the struggling Lambretta France company, which was really in dire straits, trying to survive with their last diesel cars, the BMA Amica and Casalini Bretta.
