Was looking around on youtube and I found this awesome video
http://www.youtube.com/watch?v=40yDbeukR10 It is a video of a car assembly plant from the 1930's and it is really interesting to see all of those machines making the parts for the cars. My favorite machines are those presses shaping all of the body parts. It is actually a lot more machines than I thought would be in a plant from that era.
