What have you done today with your Austin Seven

[Duncan Grimmond]

The "cup holders" are actually intakes for and air-flown tube running through the tank which carries the coolant. I was completely foxed by the design if the "radiator" but a pal who called in immediately identified the system as being the same as dairy shed milk coolers. The tubes run through the water to an outlet and in a milk cooler are vertical so that cool air is drawn in by the column of warm air rising. I imagine that there was a firm of dairy equipment manufacturers on the same street in Coventry where the Excelsior works was...
On the Forecar I suppose the faster you go the cooler it gets while the passenger panics!
