I did not see mention of the Cruiser Mk III, which introduced the Nuffield built Liberty engine. That tank brings the question, why the Liberty? I gather than Nuffield wanted a "proven" design, but an obsolete one? The Curtiss Conqueror, was almost exactly the same size and weight, but, being a decade newer design, put out about 50% more power, and had the valve train enclosed, instead of the rockers and valves exposed to the environment, as was the case with the Liberty. Given the unreliability of the Nuffield Liberty in North Africa, I can't help but think the Conqueror would have been a better choice.
