| 324 To HPS.{Horace Percy Smith - Experimental Factory Mgr} from Rm{William Robotham - Chief Engineer}/FJH.{Fred J. Hardy - Chief Dev. Engineer} Rm{William Robotham - Chief Engineer}/FJH.{Fred J. Hardy - Chief Dev. Engineer}5/MH.{M. Huckerby}28.3.39. PH.III FAN. Will you please build up two Ph.III production fan spiders with blades to E.89255 in dural. These are to be sent to Ferodos for belt testing. The last fan we sent them has failed after only 10 hrs. running. This is so short that we suspect that the blades may have been in aluminium instead of dural. Will you please make quite sure that the blade material is dural in the two new fans mentioned above.
