This is a butter churn from my collection. I hope to exhibit this at a show next summer. I may power it with a Maytag twin. I am not currently wanting to sell it. It is in very good condition, it just needs minor touching up. It is set up for a hand crank as well as engine power. But I think your arm would get tired before the butter was done. I like to have something for my engines to power to show people what the were used for.
