Does anybody know enything about the competition that led to the USN. I realized that I have nothing but the Boeing Model 374 rival design. Name and details of the request for proposals, contenders? Anything will be welcomed Antonio

As a slide rule addict (and, by way of disclosure, an ordinary member of the Oughtred Society), I'm well aware of the slide rule's proud history in aerospace design and research. Now we know that it almost certainly wasn't all done with slide rules - log and trig tables, mechanical calculators...
