| contd :- -2- louvred bonnets, so that we must expect trouble if the shutters are not used. We have made the radiator as high as permits of seeing the front wings, as wide as the frame allows, (which in its turn is as wide as the lock allows). It is as thick as is efficient, and the fan is as good in size, efficiency, and drive, as we or others know how to make it, so that the only outlet is what we propose for 'X' series - i.e. to widen the track to 58", drop the ground clearance to 10" normal instead of loaded, and so increase the fan and radiator another 10%. Every little help may make a vast difference. Generally the ignorant fill the radiator full and then try and keep it so, thinking the overflow is boiling. I am not surprised at Hs{Lord Ernest Hives - Chair}' remarks, when he has done all he can; often we feel tired after struggling through many difficulties. R.{Sir Henry Royce} | ||
