Old judo film

The YouTube channel JuYokuGoOSeisu has a number of sequences from an old judo film that have served as a pretty nice reference for me (although you'll have to wade through a bunch of other stuff to find them). They start with the basic application of a classic technique and then show a few forms of it. They were originally narrated in English, but there's a Spanish voice over covering up what the original is saying. Still, you can get a pretty good idea of what's going on just by watching.

This one, on sankaku jime, is one example (since we'll be looking at sankaku issues this week in morning class).
