If said information did exist, how many people within IBM would actually have access to it? How would IBM top-brass not see this documentation as a potential liability when the Germans became the enemy or at least when the Germans lost the war? I think that it's highly unlikely that such documentation was allowed to exist if it ever did exist in the first place. If it was allowed to exist past the 1940s, it was probably placed under lock-and-key. I doubt many of the rank-and-file IBMers would have access to it.
