The problem was further complicated by British advisors inferring that some mystical process was involved, which surely was beyond colonial comprehension. Metallurgists at Dominion Foundries and Steel (Dofasco) in Hamilton soon discovered, however, that good quality steel could take on all the desired properties through straight forward alloy and carbon adjustment. Dofasco established, through its tests in 1940, that a level of alloy well below that in allied use at the time, had optimum qualities for armour plate. The Dofasco formula was soon adopted by both American and British manufacturers. Dofasco was able to produce good plate but had difficulty with proper heat treating and straightening. Dietrich Saw Company of Galt had developed techniques for straightening large saw blades and were able to do the job with little delay. The plate was then sent to International Harvester Co. in Hamilton for punching and forwarded to Dominion Bridge Co. for hull fabrication which was done in an old plant south of Windsor which was reopened for the purpose."

I was unsuccessfully looking for my copy of Blueprint for Victory so I could post that exact paragraph. Sounds like I was looking for the wrong book. Thanks for posting it.
