Hand Controller with Speed Roller (Early)

A ColecoVision controller carrying a speed roller - the thumb wheel Coleco put near the back of the Super Action Controller, used for throttle and speed in the games written for it.

WHICH CONTROLLER THIS ACTUALLY IS matters and is not settled here. The speed roller is documented as a Super Action Controller feature, so this entry is either an early Super Action Controller or a standard hand controller carrying the wheel - two quite different objects. The catalogue holds an "early" and a "final" example, which suggests a development sequence rather than a retail product.

This one wants identifying from the unit before the note is written properly.
