OK, its all a long time ago, maybe at 88 years old the memory plays tricks. As a driver I did not do any preparation work. I just drove anything that required moving. I was short of a license for a track laying vehicle so took the test on the road in a 434? I think. It was the one with the Hiab crane. Generally I was involved with BARV, DUKW, Stalwart and Scammell down to Landrover and Austin 1800 staff car. Usually vehicles stayed in the workshop until they were proved capable of driving down a Landing craft ramp and wading ashore. With the Scammell Explorer there was a lowloader trailer with detachable rear wheels for loading. I have forgotten the make. Can anyone help please
