M4A1(75) Sherman (large hatches)
This variant was only manufactured by Pressed Steel Car (approx. 100 units produced).



M4A1(75) (large hatch hull). This tank is a transitional version of the M4A1. It has the cast hull with large hatches, but still retains the 75mm turret and main gun. It features a "high bustle" turret to improve clearance for the larger drivers' hatches of the later hull designs. It also has "cast in appliqué" on the hull sides. It is estimated that 100 tanks of this particular transitional version were built by Pressed Steel Car. Most of them were converted to Duplex Drive swimming tanks, like the one shown above (photo courtesy of Wikipedia).


M4A1(76)W Sherman
This variant was only manufactured by Pressed Steel Car (approx. 2171 units produced).



M4A1(76)W. This tank has a one-piece cast hull, a 76mm gun with a muzzle brake, large hatches and wet ammunition stowage bins.


M4A1(76)W main recognition features



The tank has large hatches.




The rear hull plate is nearly vertical, it no longer has a shallow horseshoe shape. The large grille seen here is the Barber-Colman exhaust deflector.




The engine deck plate is the same than on M4(105) tanks with large hatches. Note that an additional petrol/oil cap was added, compared to earlier M4A1 engine deck plates.




There are still two engine access doors, the exhaust deflector is also missing here, like on many monument tanks.

This variant was only manufactured by Pressed Steel Car (approx. 1255 units produced).
