A plastic moulding forms the main body of the vehicle. This moulding also comprises the top half of the boiler, the port face and mounting for the single cylinder and the bearing for the crankshaft.
The bottom half of the boiler consists of an aluminium inverted dome shape attached to the plastic frame. The small meths burner has a single wick and is located under the boiler on the chassis. There are two nipples moulded into the plastic moulding on the top of the boiler and are connected by a short length of rubber hose. This forms the boiler filler and is probably also intended to act as a crude safety valve.
The single cylinder is a single acting oscillating cylinder, 8mm bore x 10mm stroke, moulded in plastic and mounted on the top of the boiler. The piston is a simple slug of metal (aluminium?) and has no piston rod. The flywheel consists of three metal discs fitted inside a plastic moulding. The crank pin is part of this plastic piece and fits directly into a hole in the piston.
The crankshaft extends down through the main body and has a lower bearing in the chassis. A rubber band is wrapped around the end of the crankshaft and the crenellated circumference of the single driving wheel, via a 90 degree twist.
The driving wheel is mounted on the front half of the articulated chassis. An axle for the other two smaller wheels is mounted on the rear half. Steering is effected by adjusting the articulation in the chassis.
