The full sized Moonbuggy (see also pictures of the full size prop) was represented by models in various scales. The smallest was 1 inch/ 3cm long (seen here held by Sylvia Anderson). The others used most often were 6cm, 12cm and 20cm long. For the second series a 46cm long remote control moonbuggy was constructed, but was used only in a handful of episodes. All the models were made with astronaut figures which could be detached (uniformed figures were added in The Full Circle).
This model is 20cm x 13cm x 8cm, and is featured in the opening scenes of Breakaway, in The Infernal Machine, and in The Last Enemy. The front section is quite foreshortened, but otherwise it is a fair representation. It contains an electric motor to drive the rear pair of wheels.
Below is one of the larger moonbuggy models, about 8 inches/ 20cm in length. The uniformed figure shows this was the one used in The Full Circle with the 44 inch Eagle. It has a 9 volt battery, but it's not powerful enough to move it- it still had to be pulled by wire. There is still orange paint (from the astronaut figures) on the seat. The figure is ceramic or plaster. Thanks to David Hirsch.
