Made by Thomas Automatics Co.Ltd. in the late 1970s, initially for amusement parks, the Humbuggy was sold as a childrens toy by Harrods. A batch of six or so was sold to an Arab Sheik and several exported to America.
The vehicle was designed by a Cambridge student and developed by Thomas Automatics, then built by a firm in Cambridge. It used a Qualcast lawn mower engine and most were produced in orange.
There were several different designs, the one pictured is the first, where later ones had rear wheel drive and independent suspension. Later still they produced an invalid buggy which had two motors at the back with rear wheel drive and came in any colour you liked as long as it was orange. Regularly shown at the NADIC exhibitions in Brighton in the late 70s and early 80s.
