Wor.{Arthur Wormald - General Works Manager} c. to Rg.{Mr Rowledge} Da.{Bernard Day - Chassis Design} c. to Z. HY.{Tom Haldenby - Plant Engineer} ------------------------ Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} 3/AJ. 7. 5. 30. ------------------------ x7080 . AIR SILENCER 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 l to Phantom ll. We think that the proposed modifications should improve matters considerably.
