From this angle, the M46 Patton is virtually identical to the M26A1 Pershing. Each was armed with the M3A1 90mm gun, which features a bore evacuator and single-baffle muzzle brake.
This view provides positive identification. Engine exhaust mufflers are mounted on the rear fenders, and a small track tension idler is between the rear road wheel and the drive sprocket. The gun travel lock on the rear deck is raised, and the pistol port in the side of the turret can be seen. Two sockets for mounting a .50cal machine gun are visible on the turret roof, one to the front and a taller one to the rear.
A closeup of the single-baffle muzzle brake and the bore evacuator on the front of the gun tube is provided here.
The mounting of the engine muffler on the rear fender can be seen in this image, as well as the mounting bolts and bracket for the fender itself. The grille to the right of the image provided access to the transmission, and stowage mounts for the .50cal MG can be seen on the turret rear. A towing cable is routed below the muffler.
Details of the exhaust pipe connection to the muffler can be seen here. Under the turret bustle in the center of the rear deck is the center battery cover.
A closer image of the battery cover and the underside of the turret bustle is provided here.
The bow machine gun mount is shown here, and the pioneer tool stwage rack is mounted on the tank's upper hull front. The siren is visible just behind the headlight.
The apertures for the ventilator mounted between the drivers can be seen in this picture. Details of the driver's periscope housing guard, door hinge, and door hold open catch are shown, as well as the attachment of the fender mounting bracket to the hull lifting eye.
The TC was now provided with a mount for the .50cal MG in front of his position. This was ergonomically better than the mount found on the M26, which was behind the commander.
The small idler wheel in front of the driver sprocket was intended to help maintain track tension and prevent the tracks from being thrown. A shock absorber and bump stop are visible behind the rear road wheel.
The swing arm of the small idler wheel is shown here. The circular port to the right of the image is the left side brake linkage adjustment inspection cover.
The hull rear plate provides further differentiation from the M26. 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.
