| To P.N. from Hs.{Lord Ernest Hives - Chair} c. to EP.{G. Eric Platford - Chief Quality Engineer} c. to BY.{R.W. Bailey - Chief Engineer} X4240 Hs{Lord Ernest Hives - Chair}4/LG27.7.23. RE. 20 HP. COOLING. We certainly should not expect a 20 HP. car to boil in 2 miles running under full power unless there was something obviously wrong. We attach a report and chart giving results of tests with regard to Cooling. It will be seen from this that a car was run full power at 20 M.P.H. for 19 minutes on a fairly hot day without boiling.
