| To Hs.{Lord Ernest Hives - Chair} from R.{Sir Henry Royce} X.93. R2/M28.4.25. FIRING IN SILENCER. X.93. With reference to the question of firing in the exhaust we have not heard whether the boilers had any effect on this. If we are going to have the throttle valve water heated we must put the boilers on the exhaust pipes, or cancel them; We are also anxious to know whether the new head will have any effect on the above features, especially that of firing in the silencer.
