A further thought about the heater illustrated is that it might work better with an export fan. When I was using a Seven as daily transport during winter '63 I blanked off a substantial part of the lower radiator just so that the engine would run at a more normal temperature. I remember stopping at Grantham for some aluminium foil for this purpose when driving to Thirsk for the start of a particularly cold Measham. I think that was the event where one unfortunate participant got out of his vintage Bentley for a pee, slipped on the sheet ice and broke his leg.
