Armored Car Number 1.
The somewhat top-heavy design of the armored car Number 1 is apparent from this image. The wheels were shod in solid rubber tires, and hatches for access to the crew and engine compartments can be seen on the side of the vehicle. Headlights were mounted in armored boxes on both ends of the machine since it could be controlled from both the front and rear. Each machine gun had its own turret, but the rear turret did not have 360° traverse available due to its position. (Picture from Development of Armored Vehicles, volume II: Armored Cars, Scout Cars, and Personnel Carriers.)
The front of the machine is shown here. The driver had a small viewport, and could also swing the entire top-hinged front hatch upwards. Note the square hinged plate in the front of the vehicle; this could be swung up to engage the catch directly above to provide air to the engine. Other versions of this vehicle had the front plate divided into two outward-opening halves. (Picture from Tank Data, vol. 2.)
The other type of radiator armor is well illustrated here, along with the 4-wheel steering. With the vehicle's apparent ungainliness, sharp turns may have been hair-raising. The driver's large front hatch is swung open on this machine. A single proofing bullet strike can be seen on each plate of armor. (Picture available from the National Archives.)
This rear view allows us to see the relatively narrow width when compared with the length and height of the vehicle. Tool stowage and a towing pintle are visible on the rear plate, and a better idea of the turrets' fields of fire can be gleaned. Vision ports in the rear and sides can be better seen in this lighting. The backwards-facing headlights for the rear driver are mounted.

Note that in contrast to the car above, this machine has a vision port instead of a hatch in the rear plate. (Image courtesy Southern Methodist University, Central University Libraries, DeGolyer Library.)
