I've been trying to find a Sherman Mil-spec (yes, there was one), or a
war-time armor weldment/casting spec or hull drawing. It would likely say
what acceptance testing was required, including how many were destructively
tested. My best guess now, based on current practice and some scraps of
wartime info, is that large castings like turrets and hulls were
ballistically tested on a sample basis, while armor plates were tested in
the as-rolled form. Welds were likely ballistically tested in mock-up form
with an occaisional full-up destructive test.
Speaking of build numbers, I'm pretty certain the carved-up Sherman in
Wibrin, Belgium, is an M4 (as reported in the BoB Then and Now) rather than
an M4A3 as reported on the Ardennes 44 website and painted inside the hull.
It has the modified direct-vision driver's hoods. I doubt that any
remanufactured Ford M4A3s were in combat in the ETO during the BoB. Plus,
it doesn't have the prominent build number on the left hull nor hull serial
stampings that are virtual ID features for Ford M4A3s in their own right.
Unfortunately, they had already hacked out the loader's periscope, so I
couldn't get the turret acceptance dates, which would have been nice to have
considering it had a welded pistol port.
