The British 20pdr gun

I believe that the Centurion tank prototype was armed with the 76.2mm "17pdr" gun. What was really desired was a more potent gun. That gun was the British equivalent of the German 88mm L71, the 20pdr gun. This gun had an 83.4mm bore. With such as gun, the Centurion was the equal of any opponent in the late 1940's and into the 1950's. The 20pdr gun was made obsolete by the need to counter the ever larger Soviet guns. The AFV Club has a model of the Centurion with the 20pdr gun. The Centurion was the first really general-purpose British tank, and was very widely used, because of its quality.
