This may be a derby (Derby), but I couldn't find it here with the search function.
This old film from the 1930's starts out with a cool precision moto riding team, then goes into explaining the need for a differential gear in cars, and shows how it works.
I love old films like this.

Nice find, that's a really cool video.

Outstanding film. Anytime someone uses tinker toys to explain something mechanical, I'm hooked. Pretty amazing how it all just comes together in such a simple manner.
Neato!
