From this view, the M46 Patton strongly resembles the M26A1 Pershing. The turrets, front hulls, and weapons are identical. Each was armed with the M3A1 90mm gun, which features a bore evacuator and single-baffle muzzle brake. The rear hulls, however, are the differentiation points. The M46 features a small track tensioning wheel behind the last road wheel, and its engine exhaust is through two fender-mounted mufflers, which inconveniently have been removed from this tank. (Picture courtesy Armor Foto.)
This view provides positive identification. The mufflers are mounted on the rear fenders, and the exhaust port in the rear hull plate is absent. The round covers in the rear plate are transmission access plates, and the box above these housed an interphone system. The turret on this vehicle is reversed, and the gun is resting in its travel lock.
The turret hydraulic traverse mechanism is diagrammed in this image. The gunner and commander both had traverse controls, but the commander received precedence so he could override the gunner's inputs. The hand crank between the gunner and commander could be used to rotate the turret if the hydraulic system became inoperable.

A look inside the external interphone box reveals the handset is missing from this vehicle, but the control box and take-up reel remain. Two vertical hooks are in the left of the box.
