| To BY.{R.W. Bailey - Chief Engineer} from E.{Mr Elliott - Chief Engineer} c. to Hs.{Lord Ernest Hives - Chair} X.4240 E4/M9.6.22. GOSHAWK - WATER CIRCULATION SYSTEM. X.4225. X.4240. With regard to the above Mr. Royce states that a 1" diameter suction pipe from the radiator to the pump should be used, and a larger delivery pipe from the cylinder head to the radiator, if possible. This should be applied as far as can be done to the first cars in production. The larger slower speed fan should be applied carried on the existing fan bracket. There is some doubt about clearing the top water pipe with this fan. The radiator appearance is being modified at Mr. Johnson's request, and we are putting in a top tank at the same time on the radiator to hold .3 of a gallon more water.
