| X 3579 To AJL. from Hs.{Lord Ernest Hives - Chair} To ACL. from Hs.{Lord Ernest Hives - Chair} Hs{Lord Ernest Hives - Chair}/LGIO. 8. 25. Please carry on with experiments on Autovac fitting to prevent fading. Please write to the manufacturers and ask about the further six I asked them to prepare. Instruct O.O. to order the 6 fittings from the manufacturers. If they have arrived, hand one to R.D. and one to T.D. and get their opinion. We want to find how much the fitting reduces the efficiency of the Autovac. We also want you to carry on with the silencer tests and find the reason why those on 98-NK and 7-EX whistle. This is important as we want to send a car to London fitted with improved silencer. Hs.{Lord Ernest Hives - Chair} | ||
