Sometime in the early 2000's the original puppet scale car and boat props used in the shooting of the film surfaced on the Vectis auction site; I saved them here for posterity, complete with the original text as found at Vectis' site.
Gerry Anderson The Investigator eight-wheeled sports car original film prop, 1973, radio controlled, fitted with a petrol fuelled motor-bike engine, used in a twenty-three minute pilot episode of a new project that did not continue to further production; designed by Reg Hill, who had made many of the props for Gerry Anderson's other productions, including Thunderbirds, Stingray and Captain Scarlet. This car, and the following boat, lot 4540, were manufactured by Space Models of Feltham, car has storage damage and missing some parts, would benefit from sympathetic restoration, untested, 87"/221cm long. NB: The Investigator was to be the final Supermarionation production. Three Thunderbirds voices were used — Peter Dyneley (Jeff Tracy) as The Investigator, Shane Rimmer (Scott Tracy) as John and Sylvia Anderson (Lady Penelope) as Julie.
