It is interesting for sure. The war production board had A LOT of power and they could get things done.

I have a book someplace Otis War Production (or very close to that name) It goes into what Otis Elevator made during the war. What comes to mind is landing gear for planes, attenuators for AA guns, engine cases for Curtis Wright, some electronic stuff and several other items. Now it get interesting they made machine tools for other people, they built Norton surface grinders and Mori (?) screw machines. The builders could not keep up, Otis had the equipment and ability so they got to build them. They didnt have an Otis name on it and most folks would have never known. Otis built the Norden sights in the 1950s. Ibm made the Nordens during WW2 also. Ibm must have loads of interesting items for the war!

Another interesting thing in the Otis book is that they had to make a small grocery store in the plant so workers could buy food with out going out to shop as the hours were long.
