"Ethel" is an early-production M8 and features mine racks between the first and second road wheels. The aperture for the gunner's M70D telescope is visible on the near side of the gun shield; the coaxial MG is on the opposite side of the 37mm gun. The drivers are provided with two hatch covers, and on this vehicle the driver's hatch covers are open. The top hatch cover swings to the outside of the vehicle, while the front hatch cover swings down onto the front slope. The front hatch covers feature both a direct vision slot and a protectoscope, and there is another direct vision slot outboard of each driver. The vehicle's siren is just inboard of the right-hand headlight group. The .50cal MG is mounted on the Ford-designed folding mount.
This car is fitted with the M49C ring mount instead of the Ford-designed machine gun mount, and can be contrasted with the other vehicles on this page.
The machine gun ring mount was welded off-center to the rear of the turret to adjust for the removable plate that facilitated extraction of the 37mm gun.
The open turret is highlighted in this view. Seats for the turret crew flank the 37mm gun, and pioneer tools (axe and shovel on the left, disassembled mattock on the right) can be seen stowed on the fenders between the front and intermediate axles. A towing cable is strung along the hull's right side. The handles and hinges for the engine compartment doors are visible on the rear of the hull. A 12' x 12' (3.7m x 3.7m) paulin is stowed on the rear of the turret, and four blanket rolls for the crew are hanging off the turret sides. Between the turret and the engine compartment doors is the fuel tank cover; the filler was under a hinged portion of the right-hand side of the cover. (Picture from TM 9-743 Light Armored Car M8.)
The driver's position is shown here. His steering wheel, instrument panel, and gearshift selector are visible, as is the compass in front of the assistant driver's seat. Just beyone the compass is the protectoscope in the assistant driver's closed front hatch cover.
A view of the opposite side of the driver's compartment is shown here. Note the carbine stowed to the driver's left and the spot for a fire extinguisher bottle near the bottom of the image. When the transfer case ratio selecting lever was in the down position, high gear for the transfer case was selected. When this lever was swung up, the transfer case was shifted to low gear. Before engaging the low ratio, the front axle was to be engaged by swinging the front axle engaging lever up. The vehicle was to be traveling at no more than 5mph (8kph) when changing from the high to low ratio. (Picture from TM 9-743 Light Armored Car M8.)
The right side of the turret is illustrated in this image. Thirty-seven millimeter ammunition lines the far side, and the black coaxial machine gun can be seen on the opposite side of the 37mm gun mount. A total of 16 37mm rounds were stowed in clips in the turret. The gunner's sighting telescope is visible, and the top half of his elevation handwheel is near the bottom of the picture.
This view is looking in through the open driver's hatch. The remaining 64 rounds of 37mm ammunition were stowed in the righ-hand sponson behind a sliding door.
This late-production vehicle featres stowage bins between the front and center axles instead of the earlier mine racks. The front leaf spring can also be contrasted to the smaller spring on the above car.
The positioning of the folding .50cal MG mount can be seen here. It was attached to a plate in the turret rear that was removed to allow the 37mm gun to be taken out of the vehicle more easily.
The installed engine is shown here. With the transmission and accessories, the engine weighed ~1030lb (467kg). It displaced 320in³ (5200cm³) with a 4" (10cm) bore and a 4.5" (11cm) stroke. The engine was ungoverned, and responsibility to prevent over-revving the engine resided solely with the driver. (Picture from TM 9-743 Light Armored Car M8.)
This view is looking toward the rear of the vehicle. (Picture from TM 9-743 Light Armored Car M8.)
This view is similar to the one above, but is looking forward from the vehicle's left rear. (Picture from TM 9-743 Light Armored Car M8.)
