Phantom, I remember the old butter churns also, with the hand crank and wooden paddles. If a person had never seen one before, it would be great for one of the "what is it " pictures even !
We used to make our own butter sometimes, too, but we did not have one of the old butter churns, so we just put the cream in a jar, ad passed it around to everyone in the family and took turns shaking it, until it finally turned into butter. It was kind of a long process, and not much butter at the other end of all that shaking, so we didn't do it very often, we usually just used the cream otherwise, or left it in the milk for wonderful whole milk, which the kids absolutely loved.
