General Motors Corporation in World War Two / WWII

This 1942 publication is references some of the work being done at the various divisions on how they have improved production of war goods through automotive mass production techniques.  While today mass production and assembly lines are taken for granted, they were still new and not used in many industries at the start of WWII.  Actually World War Two for the US brought these methods to industries like ship building and aircraft assembly where they had not had the needed volume to use them before.  Also material substitution is mentioned as a way to conserve limited raw materials.  In researching all of the WWII auto makers they all used the methods described below.  Luckily General Motors was a lot better about publicizing what it did in these areas so we could read about it 70 years later.
