I have limited research material on this Sherman adaptation. Can anyone verify which Sherman variants would have been used for this operation? I know that they were very limited and that the 738 and 739 Tank Batt. used them along with the 6 Armored Div. The only shots I have show it mounted to a M4A1 with the
75mm gun, and what apears to be a M4 with the 75mm gun.
