Original 8-way, rotary joystick controller used on SNK's rotary games such as Ikari Warriors, Victory Road, Time Soldiers and other rotary arcade games. This is a used joystick, it has some typical wear, but should clean up well. It has been tested and works fine.
We are not sure of the manufacturer on this one, it has a red ball, tapered stick and microswitches on the base. See pictures for more details.
