This post is provoked by a video from Nicholas Moran, AKA the Chieftain. In the course of discussing the development of the late-war Sherman with the 76mm in the T23 turret, Moran at one point seemed to imply that some M4s were up-gunned in the ETO by shoving the 76mm into the original small turret. I imagine such vehicles would have been pretty close to the postwar M4A1E6/M4A3E4. Of course the M4 had been designed with a rather Catholic turret which could in a pinch take the 3-Inch gun or a 105mm how. Now, does anyone here know anything about any such field modifications? Did they happen, or am I misunderstanding Mr. Moran? I have Zaloga's Osprey book on the Sherman and he doesn't say anything about the matter. And yes, I do know some Sherman Jumbos were re-armed with the 76mm in the ETO, but they had the T23 turret.
