That was a great video, thank you! Knowing basic gear mechanics helps a lot in understanding how cars function.

This 1937 video about differentials is also enlightening:

Why is it that old tutorial videos are so thorough and informative?

It was also a big deal to make a film like this. Today you can just prop up your phone on something and go to town, but these videos would have been a huge amount of work. Once you're putting in that much work, you had better make sure the result is good.
