| XV027 To Sg.{Arthur F. Sidgreaves - MD} from E.{Mr Elliott - Chief Engineer} E.1/HP.10.9.32. c. Wor.{Arthur Wormald - General Works Manager} Hs.{Lord Ernest Hives - Chair} By.{R.W. Bailey - Chief Engineer} X8770 re Sg.{Arthur F. Sidgreaves - MD}4/E.8.9.32 - 20/25 Chassis, J.3. and Peregrine etc. Further to our memo EG/HP.9.9.32, the experimental department say it would be a definite advantage if we adopted the side drain plug on the 20/25 chassis, as used on the Phantom, and that this alteration can be easily adopted as it does not interfere with interchangeability and does not require a 10,000 mile test. We are therefore, proposing to do this. With further reference to item 4 with regard to closing the radiator shutters by hand when standing, we agree that the spring we are proposing to add does not meet the requirements in this respect. The desire is for some device whereby the radiator shutters can be closed down manually, or will close down automatically the moment the engine stops. This could be done by adding more features to the car, preferably a device operated by oil pressure, but we question whether it is worth the extra expense and complication. We think it is a definite advantage only where cars are being operated under conditions of very low temperature where there is liability of damage due to freezing. Under these conditions it is usual to take precautions not to leave the car exposed. E.{Mr Elliott - Chief Engineer} | ||
