R. Edwards & Sons rebuilt two 15-ton Scammell tractors as Showtrac-alikes. They are:
CHK652 'The Moonraker'
FEV858 'The Churchill'
Neither of them were re-built with the wider cabs.

CHK652 is part of the Scarbourgh Fair Collection and was photographed at the Great Dorset Steam Fair on August 28th 2008. (Jim Wells)
