Thomas Hugh Parker, son of Thomas Parker, is believed to have designed the Electric Construction Co (E.C.C.) Bushbury which was entered in a race for self-propelled road vehicles from the Crystal Palace to Birmingham, cancelled at the last minute due lack of entrants. This is very likely the machine for which the Star Cycle Co built the rolling chassis. Only one was built, which, as may be seen in the illustration, was controlled by reins.
