Prototypes & Mockups
Spacex card back photograph shows a Tractor T-5 fitted with five-spoked wheel hubs, showing the black of the wheel through the holes between the spokes. The window glass has almost no tinting, and reveals a detail moulded in green inside that isn't present in production models.
An illustration by Eric Eden in a feature in TV21 magazine #87 of 17 September 1966, showing the vehicle towing a longboat in the 2066 celebrations of the Battle of Hastings 1000th anniversary.
The cab design of both vehicles is based on that of the Thunderbirds Transmitter Truck (aka Jodrell 6) which subsequently reappeared in this TV series in other guises and colours.
