The Churchill Great Eastern was a ramp tank designed to overcome much greater obstacles (both horizontal and vertical) than could be bridged by other bridges. The tank carried a long ramp which sloped upwards from rear to a height of some 20 feet at the front. A second ‘flying’ ramp was hinged to the first at the front and was stowed folded back a top the lower ramp. Hinged to the rear of the lower ramp was a third short ramp that reached the ground. This would usually be held raised at a near 45 degree angle whilst stowed. The Great Eastern was deployed by first driving a close a possible to the obstacle, then the upper ramp was propelled upwards and over by two groups of 3″ rockets. The Great Eastern could provide a span of some 60 feet being able to cross a 12′ high 5′ wide wall.

This is a big print and needs a well tuned printer as tolerances are quite tight! The hinge pins are brass wire.
