The .50cal MG is mounted on this vehicle, and the drivers' hatches are closed. The car's siren is just inboard of the headlight guard in front of the assistant driver, and the blackout marker lamps are fastened above the service headlamps.
This vehicle has mine racks between the front and intermediate axles; late production M20s replaced these racks with stowage bins. The rear stowage boxes can be seen above the rear wheels; handles and padlocks indicate their position. This vehicle is fitted with sandshields,which were sometimes removed in action since they could fill with mud.
The rear of the car is shown here. The exhaust pipe for the engine exits on the right side, and the towing pintle and shackles are along the bottom of the vehicle. The right-hand tail lamp has a blackout stoplight in the upper cartridge and a blackout taillight in the lower. The left side tail lamp housing contained the service taillight and service stoplight in the upper cartridge and the blackout taillight in the lower. The hinges for the rear sandshields can also be seen.
This later-production car has the stowage boxes instead of the mine racks between the front and intermediate axles. The two-piece drivers' doors are open, and a .30cal machine gun is mounted.
The car's interior and the position of the machine gun ring mount relative to the roof opening are visible in this top-down view. The portable 4lb (1.8kg) CO2 fire extinguisher is secured at the right rear of the passenger compartment. (Picture from TM 9-743 Light Armored Car M8 and Armored Utility Car M20.)
The drivers' seats can be seen through their open hatches. Wooden troop seats ran along each side of the passenger compartment, and a similar seat for the gunner was mounted at the rear. All of these seats as well as the commander's table could be folded up when not required. The table could also be removed. (Picture from TM 9-743 Light Armored Car M8 and Armored Utility Car M20.)
The ring mount M49 is highlighted in this image. (Picture from TM 9-743 Light Armored Car M8 and Armored Utility Car M20.)
The ring mount M66 is shown from the rear. It dispensed with the skate carriage, and instead used roller bearings to rotate the entire inner ring on which the machine gun was mounted. (Picture from TM 9-743 Light Armored Car M8 and Armored Utility Car M20.)
