For those interested, the Scammell shown by Bob at the top of this thread is termed 6x6 'Explorer' and has a powered front axle which because of the extra weight, the previous ballast weights at the front of the vehicle were not needed. It also has a Meadows 6 cylinder petrol engine of just over 10 Litres, giving a top speed of around 25 mph, 3 mpg and a winching capacity of 15 tonnes.
These trucks were specifically designed as rescue and recovery units for the Army and "THOR" is a 1954 example and one of only 726 built. Here is another picture of her...
