Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}2/MJ.7.5.30. AIR SILENCERS CARBURETTOR. The attached report shows that we still lose more power than is desirable with this silencer. with it we drop half the increase that we got by going from Phantom I to Phantom II. We think that the proposed modifications should improve matters considerably. Hs{Lord Ernest Hives - Chair}/Rm{William Robotham - Chief Engineer} | ||
