Those are Lightfour Imperial cylinders. The Handifour was dropped because it was thought to be taking sales away from the more expensive Imperial. Mechanically they are identical. They also share some parts with the Midget Racer. The Lightfour Imperial was good enough to take our AOMCI treasurer, George Emmanual, on a 100 mile cruise up the Suwannee River a few years back. . . 😆
