Hi alan, i well remember the winter of 1963, i was making regular trips to london and birmingham at the time in a ford 5cwt thames van with no heater and no roof lining, icicles used to form from the condensation from the metal roof and the only way you could clear the windscreen of freezing fog,(remember that) was to open the bonnet which used to open from the windscreen end and prop it open with a block of wood so that the heat from the engine would keep the screen defrosted, there were no screen washers either and some of the journeys were a nightmare, this was the time when the diesel used to freeze and wax up and it was not uncommon to see lorry drivers lighting fires under their fuel tanks, also front wheel drive cars were not the norm and we had to reverse up icy hills to obtain some grip, the good old days, i don't think !!!
