Old style windmill water pumps used in remote prairie or outback locations for livestock, etc, generally had a speed governor that uses heavy iron balls as part of the mechanism. Some get sold as cannon balls.

Those could be easily excluded by the initiated, as they leave visible marks of their suspension rings.
