Why Gun Tractor Shape

[Tom Millward]

Hello guys,

Just a thought from a tank designer’s perspective, the sloping back would have given the gun No1 (the commander who stands out of the top hatch) a good view over the back of the gun tractor and allowed him to see the top of the limber, which may have helped the driver in maneuvering the awkward combination, particularly reversing. In the later Morris gun tractors the roof is squared off. Much better for stowing kit, but the rear view is obscured.

I stumbled across this statement today will discussing Morris FAT designs:” while early Quads had the distinctive "beetle-back" shape, from 1944, the final model, the Mark 5, moved away from this characteristic shape as it was realised that it was too readily recognisable from the air, and therefore instantly indicated the position of an artillery unit. The Mark 5 was therefore given a more square body with a canvas-covered cargo space at the rear which made the vehicle resemble an ordinary cargo truck.”

Has anyone heard of this before

Hi Niels
I have not heard that before, but it can be an answer as simple as it is effective. Sometimes we tend to complicate the answers.
