In 1936 Chevrolet commissioned a film to be made showing how their cars were made.

Lots of interesting stuff in here -- there was an amazing amount of hand work being done, but there was also the beginnings of automation in the section that made the frames.

While the stamping presses had some safety features (two hands needed on the buttons to start their motion), a modern OSHA inspector would have a coronary with all the unguarded moving parts.
