90mm Self-propelled Gun M56 at the American Armoured Foundation Tank Museum.

The very basic design of the M56 can be seen in this picture. Creature comforts, or even weather protection, were nonexistent. The mannequin in the vehicle is sitting in the gunner's position, and the seat for the loader is visible on the fender stowage box just in front of the gunner. The right-hand exhaust pipe for the engine can be seen exiting the front slope directly below the blast shield.

Air intake and exhaust grilles can easily be seen on the front of the hull. The grille on the very front of the hull covers the transmission, and the engine access door, which would normally have locking handles on its forward corners, is directly behind. The engine exhaust pipes exit to each side of the rear of the engine compartment, and discharge over the fenders. The gun would normally end in a cylindrical blast deflector instead of the T-shaped muzzle brake present on this machine. The arrangement of the gun travel lock can also be seen.

A closer view of the gunner's position is provided here. The gunner used a telescope T186 for aiming the gun, and his right hand is resting on the traverse handwheel.
