Ammunition Trailer M28.

Each M19 was provided with an ammunition trailer M28, which was a standard 2-wheeled, 1-ton cargo trailer that has modified with clamps to hold twenty 16-round ammo chests M14. The trailer came with a canvas cover to protect it from the dust and mud kicked up by the vehicle's tracks. (Picture from FM 44-62 Service of the Piece, Twin 40-mm Gun Motor Carriage M19.)

The lengthened chassis of the M19 necessitated an additional return roller compared to the M24 Chaffee on which it was based. The large 40mm gun turret occupied the rear of the hull, and the engine was moved to between the turret and the drivers' compartment. Pioneer tools are stowed on the hull front, and spare 40mm barrels are kept on the hull in front of the turret. An antenna mount is visible on the front hull plate between the drivers; the antenna would lay towards the vehicle's rear and would be almost horizontal when present. Ammunition bins were installed on the hull around the turret, and a battery box occupied the central position on each fender.

The auxiliary generator would be mounted on the right-hand fender behind the battery box, but it is absent on this vehicle. There are holes in the ammunition box facing us, however, that show where the generator's exhaust pipe and guard were mounted diagonally downward across the ammo box.

This vehicle has a generator mounted, and its presence shows how the original routing of the right-hand exhaust pipe was precluded.

Details of the single exhaust exit and its guard are shown here. By contrast, the dual-exhaust of the M19 had a pipe connected to the ammunition stowage bins on each side of the turret.

Some details of the turret interior can be gleaned from this image. A direct fire front speed ring sight is visible on each side of the gun shield, and the guns' automatic loaders occupy much of the space in the center of the turret. The radio blisters in the turret sides are apparent, and a radio is installed in the right-hand side. A packing case for the direct fire sights could be stowed in the cleft of the left-hand gun shield, but it is absent on this vehicle.

The revised engine deck is highlighted here. The engine compartment grille doors are between the turret and the spare barrels, and the guard for the engine exhaust pipe is pointing toward the lower right corner of the picture. A cover for a gasoline tank filler is at the bottom of the image, and a similar one could be found on the opposite side of the vehicle

Details of the assistant driver's door and the front antenna mount can be seen here. Both drivers were provided with a periscope M6 in their hatches.

The left-hand driver's position was inherited from the M24. The accelerator pedal is on the right, and the neutral pedal is in the center. The steering levers flank the driver's seat, and the vehicle's data plate is just below the instrument panel. Visible on the instrument panel, from left to right, are two circuit breaker reset buttons, the left engine tachometer, and the ammeter. The clip to the driver's left was for stowage of a .45cal machine gun.

The drivers were separated by the controlled differential to the front, and the spare periscope and periscope head box sits atop the front main propellor shaft. The large black-tipped lever is the transmission unit shift control lever. The large cylinders in the rear of the driver's compartment are the engine carburetor air cleaners.
