Electrons?," is the question asked. Answer: "The magic about electrons is man's ingenuity in putting them to work. The magic about electrons is their promise of service in marvelous ways only hinted at in the last few years. Now harnessed for war, the science of electrons will later work to enrich the peace. Working in close cooperation with Army and Navy engineers, Delco Radio has applied its knowledge and skill in putting electronics actively and effectively into the fight for Victory. In Delco's laboratories, principles are explored and exploited; in Delco's engineering departments, designs are evolved to apply these principles; and on Delco's production line, complete equipment is manufactured with the speed and skill that only a large manufacturer of precision radio instruments can bring to such work."
