Da.{Bernard Day - Chassis Design}Rm{William Robotham - Chief Engineer}/HPS.{Horace Percy Smith - Experimental Factory Mgr} E/HDY.{William Hardy}2/HP.24.3.37. Shock Damper Governor Unit. With reference to Rm{William Robotham - Chief Engineer}/LES.15/HP.22.3.37, it will be seen that the recommendation of the Experimental Department is that provision should be retained for the suction filter on the Wraith III but that, unless we hear to the contrary, the filter is not to be instructed. Therefore, as far as the Wraith is concerned N.Sch. 5092 may not be required but it should be applied in due course to the Phantom III on which the filter is to be retained. E/HDY.{William Hardy} | ||
