...and this was called Piollet N°5. He built his 1st car when he was 10, the 2nd at 11 and another at 14. All but the #5 were entirely (engine and wheels included) made of wood and obviously not functional.
This one (#5) was started in 1955 with a Aubier & Dunne engine.
It was later scrapped to retrieve the chassis for another Piollet: a barquette with 2 engines still extant.
