This vehicle was adopted from a King touring car. Its fenders were reinforced planks that could also be used to cross ditches. Initially, the rear of the car stepped down from the cab, and a door was provided in the vertical portion of the step. The car was fitted with pneumatic tires and wire-spoke wheels (dual wheels on the rear). A later version known as the King-Eight featured a sloping rear face with a folding door and was eventually fitted with wooden spoke wheels with solid tires. The Marines acquired eight vehicles, and fitted at least some with an automatic 1 pounder gun or Lewis machine gun.
