The type J tractor represents the bold and inventive spirit of Citroën. It's the first to be equipped with 4 large driving wheels. There were 3 prototypes built. The first 2 which belong to the "Conservatoire Citroën" performed tests at the test center "La Ferté Vidame", one of them continued its program at the "l’Abbaye de Soligny la Trappes". Indeed, difficult to find a more closed place with more secret interlocutors than the monks. We have no news from the third tractor type J...Was it built? Was it destroyed at the end of the program? Nobody knows !
There is only one fuel gauge made of wood and stamped "TRACT N3" which makes us think that the third type J exists.
