Landing Vehicle, Tracked (Armored), Mark 4 at the World War II Vehicle Museum and Learning Center.

This is an earlier-production LVT(A)4, as evidenced by the single .50cal MG mount on the turret rear. The propelling grousers on the track are obvious, and a hull escape hatch is open near the cab.

The hatches are open on this vehicle. The driver was provided with a direct vision hatch to his front, and both he and the assistant driver had periscopes in their overhead hatches. The lack of a bow machine gun in front of the assistant driver is obvious in this view, as is the paddle design of the track grousers. Mooring ties were provided at each corner of the hull.

The exhaust tips for the radial engine flank the numbering on the rear of the hull, and the glare of the taillights can be seen outboard of the exhausts. Stowage for a towing cable is also provided. Splash deflectors are just behind each track.

A close-up of the suspension is shown in this image. The torsilastic suspension was composed of rubber bonded between the hollow shaft on the pontoon and the outer road wheel swing arm. Details of the chain-type track can also be seen.

The 75mm howitzer was encased in a flash suppressor, and the howitzer barrel can be seen inside the suppressor. The .50cal MG is mounted on the turret rear, and details of the drivers' hatches and periscopes can be seen.

When all the hatches were open, the vehicle interior was a decently airy place. This view is looking in from the starboard hull escape hatch towards the driver's position.

This vehicle features vision blocks in the turret side, and the angular counterweight attached to the top of the howitzer flash hider can just be seen behind the assistant driver's periscope. (Picture from Tank Data, vol. 2.)

The 1951 modification to the bow of the vehicle is obvious when compared to the machines above: the bow's volume was increased, and the driver was given a vision cupola. The turret was also changed, and new vision blocks can be seen around its top. Note the counterweight attached to the base of the howitzer barrel for the stabilizer system.
