In the 40's I wonder how many of the parts were done on automated tools. They would not be "CNC" but they might have been build on specialized tools that only make one kind of part. I think this is a lost technology. I worked a little bit on aircraft and what I saw was a huge dependance on jigs, fixtures and purpose built tools that made just one part, over and over. I was just an intern doing production drawings on a computer plotter but got to walk around and look at the manufacturing now and then
