hi
I drove one of these Scammel when I worked for ICI Wilton. Also the older Scammels with Gardener Engines.Does the one on show have the Leyland engine. Most of the old scammels had a top speed of about 25/30 mph. But the speed of the Leyland could put the wind up us.
Maybe see you at the Dorset show.
cheers
