The second of eighteen different designs for an assault tank to break through enemy defensive lines. The designs were completed by May 15, 1943. No prototypes were built, but the project helped to set the stage for another heavy assault tank, the A39 Tortoise.
The kit comes in a sturdy flip top box with the computer created illustration of the model on the top. The parts come in several bags to keep everything, more or less, protected when shipped.
