One piece crank removal

Hi there. I am not quite sure how to remove this one piece crank, pictured at the end of this post.

It's from a Columbia Torpedo, which is an old bike. It belongs to a friend of mine, and I am doing a complete teardown to clean it and rebuild it, in hopes of making it look great, and to learn more about bikes.

The videos I have seen on one piece crank removal don't seem quite right for this crank.

Any help would be great. And I've posted a picture below the crank picture so you can see the whole bike, because it's sweet.
