| x 4190 PN{Mr Northey}/15/DB{Donald Bastow - Suspensions}8.12.19. From P.H. to B.H. c. to E.B. Whilst the cooling effect of our Radiator is being reduced . with a view of meeting the Piston Knock difficulties - are you satisfied as to what extent we are running into the difficulty at the other extreme by enabling water to boil when cars are running continually in the country such as the run from Derby to London. Holgate tells me that when driving the Trials Landaulette 1.L.W. to London, the water boiled - in fact about 1 gallon was lost. I shall be glad to have any information or remarks on this point. P.H.
