Churchill Mk IV (1,622)
The IV was the most numerous Churchill produced, and was virtually identical to the III, the largest change being a return to the less costly cast turret. The Mark V 6 pdr was fitted with a counterweight on early models. Some were retrofitted with 75mm guns (see "NA75", below) from Sherman tanks. Others were up-gunned with British 75mm guns, creating the Mk IV (75).
