| -5- Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}1/BE.28.11.32. Cont'd.{John DeLooze - Company Secretary} Summarising the results, we should recommend the intermediate size of silencer of the type above the induction pipe as being a good compromise and attach a photograph thereof. The silencer adjacent to the intake may be considered less unsightly and a sample will be available for inspection very shortly.
