Did you ever wish you could have toured an auto parts factory back in the day so you could have watched them build starters, generators, voltage regulators, ignition points and spark plugs,
the parts we have all bought and installed dozens of times over our lifetime. I have always wondered what those factories must have been like. Imagine how many spark plugs they built in a day...thousands no doubt.
Well you can wonder no more because I found a two part movie tour of the Auto-Lite Auto Parts Company from 1940, that not only show the parts being manufactured but tells what factory location built the parts shown. Also shown is the engineering behind the parts and how those parts are tested before they went into production. Last but not least is a slide show at the end showing all of the parts manufactured by Auto-Lite.
