I went in with an expectation of it being completely different. And there is much more manual labor in 1939. It's dirtier, and grittier, but mostly for the steps we don't see in the Toyota video, as for example the motor comes in one block, and we don't see how it's built. But on a high level, both videos look like the same process. You can find many steps, like the stamping, the welding, the final assembly, that look nearly unchanged in 85 years, save for some automation with robots, and some quality-of-life improvements in the assembly, where people don't have to lug around heavy parts.
