M4A3E8, could it's turret hold a 17 pounder?

The_Chieftain: The answer is 'no', and it's part of the reason the 75mm tank remained in production. The British could not easily convert the improved turret to mount the 17pr and specifically requested 75mm tanks. Interestingly, the American came to a similar conclusion, deciding that the 75mm could not be easily installed into the T23 turret either. The problem is that the trunnion on the larger turret is too far forward for the gun to mount correctly. I have the test report around somewhere, I was planning on writing a brief article about it some time ago.
