This one is standing at a parade field of Fort Jackson, Columbia, SC. Jackson like Andrew Jackson, the President. The museum curator told me it was a prototype flame thrower called M4 E1313 (I may be wrong, that's what I wrote down in a hurry). he said only internal parts inside the turret were changed. To me it looks like a regular Sherman. If anyone cares to add or correct me, that'd be nice. It does have 4 hole in the middle of the barrel, at the bottom part, I assume deactivation holes?
