But industry consolidation was inevitable, and accelerated by the Great Depression of the 1930s. During those years the French auto industry was dominated by three firms: Renault, Peugeot and Citroën -- the latter, having fallen on hard times, was taken over by Michelin, the tire maker. Lesser firms were being squeezed out of the market and sometimes resorted to preservation strategies that might strike us today as being odd, yet were occasionally used in even the USA.
The strategy the present post deals with is where a smaller, weaker company sells cars built from components of cars from stronger makes. Examples here are Berliet and Licorne.
For the 1939 model year, Berliet turned to Peugeot to body its Dauphine line. As can be seen above, from the cowling on back, the body is strictly Peugeot 402 B (the largest model in Peugeot's line at the time). The front end borrows heavily from 1937-vintage American styling.
Licorne's borrowing for 1938 was even more drastic. Besides having a Citroën body, this Licorne model also had a Citroën motor and transmission -- necessary because the Citroën was front-wheel drive and therefore had no structural provision for a driveshaft and powered rear wheels. This Licorne is essentially a Citroën with a different grille.
UPDATE: See Comments for a discussion of the Licorne's running gear and motors that runs counter to my speculations.
