Hand Controller with Speed Roller (Final)

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. This is the "final" of a pair in this catalogue, the other being an earlier version.

WHICH CONTROLLER THIS ACTUALLY IS matters and is not settled here. The speed roller is documented as a Super Action Controller feature, so this is either a late Super Action Controller or a standard hand controller carrying the wheel. The early/final pairing suggests a development sequence rather than a retail product.

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