90mm Gun Tank M47 Patton 47.

The turret is reversed in this front 3/4 view, and the 90mm gun is secured in its travel lock. This early-production tank is seen with a single-baffle muzzle brake. (Picture from TM 9-718A 90-mm Gun Tank M47.)

The location of the return rollers can be better seen with the dust shields absent. This tank is fitted with the later cylindrical blast deflector, and is missing its rangefinder and rear compensating idler wheel. The port in the gun shield for the coaxial machine gun has been plated over.

Contours of the turret and gun shield can be seen in this image, along with the absence of the ventilator that was present between the drivers on the M26 and M46. The gunner did not have a sighting telescope; the stereoscopic rangefinder was his primary sight and his periscope was his secondary sight.

The long turret bustle can be seen here, which was elongated further with the addition of a stowage box at the end. This early-production tank is not fitted with the rangefinder, and the blanked off apertures for the rangefinder can be seen at the top of the turret near the front.

The rounded nature of the top of the turret bustle can be gleaned from this image. The inlet for the ventilator blower is in the foreground, and next to it is an antenna mount. A second antenna mount can be seen on the left side of the turret.

A closer look at the rear of the cupola shows where vision blocks would be visible if not covered by diamond plate. The loader's hatch opened to the front, and assisting springs can be seen connecting it to the roof.

Looking at the turret roof, there is a large removable plate above the rangefinder and gunner's periscope. The loader's fixed periscope can be seen on the right of the image, and the commander's later-style cupola is behind the machine gun pintle stand, which was heightened and relocated from the early tank in the technical manual images above.

The position of the gunner's periscope in front of the commander's cupola is seen here. On earlier tanks, the .50cal machine gun pintle stand was farther back on the turret in a less usable position.

The manual control lever (also called a "wobble stick") served to steer the tank as well as select transmission gear ranges. Four gear ranges (from front to rear: neutral, low, high, and reverse) were available, and shifting to low or high from high or low could be accomplished by simply selecting the desired gear range. Shifting into reverse from low or high required using the finger lift trigger or hand grip handle. When in reverse, the rear of the tank would swing to the right when the lever was pushed to the left, and vice-versa. Pressing the hand grip handle was necessary to shift to or from neutral.

A closer view of the gunner's controls are shown here. The elevation and traverse adjusting knobs were used to adjust the speed of elevation and traverse. The knob in the lower right of the picture is the elevation cylinder control valve, used to supercharge the elevation cylinder when shifting from power to manual turret operation.

The front wall of the turret is the subject of this image. This early tank was not fitted with the stereoscopic rangefinder, so the periscope T35 was substituted as the main gunnery sight. (Picture from TM 9-718A 90-mm Gun Tank M47.)

The commander was also provided with a power traversing and elevating control handle. The TC could override the gunner's inputs by squeezing the override lever against the control handle. Traverse was accomplished by turning the handle in the desired direction, and elevation was done by turning the top of the handle towards the front or rear of the turret.

This is a right front view of the Continental AV-1790-5B engine. Each of the two cylinder banks was provided with its own carburetor. Bore and stroke for each of the 12 cylinders was 5.75", yielding a displacement of 1791.75in³ (29,361.4cm³). Maximum governed speed with full load was 2800 rpm, and the dry weight with flywheel and transmission adapter was 2505lbs (1136kg). (Picture from TM 9-718A 90-mm Gun Tank M47.)

This is a late-production vehicle fitted with the T-shaped muzzle brake and solid periscope guards for the gunner and commander's cupola, which can be contrasted with the tanks above. The rangefinder blisters can be seen on the sides of the turret near the top.

This picture is of the left-hand M12 rangefinder blister. The M12 was a stereoscopic rangefinder, and while having the potential of being more accurate than a coincidence rangefinder, the stereoscopic type proved difficult to use. It involved trying to align a set of marks so that they appeared to be at a similar range as the target (a procedure tankers dubbed "flying the geese"). However, this visualization process is difficult for a percentage of the population, and this type of rangefinder was replaced on the M48A2C tank with a more user-friendly coincidence type.

This detail shows the auxiliary track tensioning idler behind the number 6 road wheel. The addition of this wheel helped keep the track from becoming excessively slack and thereby helped prevent thrown tracks.
