Hi there.....I think I am beginning to realise these are as rare as manure from a rocking horse, but here goes anyway. Does anyone have one of these early radiators in any condition please ? I am specifically looking for the early type which has no cap on its header tank, but couples to a metal expansion tank, which houses the radiator cap (the same as shown in the attached photograph). I am based in West Surrey, but am prepared to travel for the right piece of equipment.....thanks in advance
