| To Sg. {Arthur F. Sidgreaves - MD} From Hs. {Lord Ernest Hives - Chair} c. to Wor. {Arthur Wormald - General Works Manager} c. to PN. {Mr Northey} X 7941. Hs. {Lord Ernest Hives - Chair} 5/MJ.7.9.31. 25-EX. CAR. 10,000 MILES. Replying to Sg. {Arthur F. Sidgreaves - MD} 16/El.9.31. The only standard method we have to improve getting the hot air away is to fit a louvred bonnet, which we recommend for hot countries. The new shutters are not as efficient as the louvred bonnet in this respect but having shutters which can easily be opened must help to reduce the temperature of the air under the bonnet.
