fact or fiction
How interesting. This "test shot" business ... is this a country specific quality assurance method?
I am intrigued by the thought that a rifle round was discharged against a hull plate, and the same plate eventually ends up as a portion of an assembled hull. Is this an urban legend or factual?
There are regularly spaced hardness standard testing marks on Canadian light armour plate as well as the more commonly visible and commented on straightening marks. The American owned company responsible for heat treating and straightening 45,000 tons of wartime production Canadian light armour plate stamped their company logo into the plate. Some side plates on Canadian U.C.'s also display a four digit serial number.
As for an assembled Canadian production vehicle showing hardeness testing tool marks attributed to a fired rifle round, or a documentation trail to support the theory, that is quite elusive.
Bob, Justin, can you elaborate?
