| To HPS.{Horace Percy Smith - Experimental Factory Mgr} from Rm{William Robotham - Chief Engineer}/Swdl.{Len H. Swindell} c. Rm{William Robotham - Chief Engineer}/Wym.{G. Harold Whyman - Experimental Manager} g 600a Rm{William Robotham - Chief Engineer}/Swdl.{Len H. Swindell}6/MH.{M. Huckerby}17.1.38. 26.G.VI. In order to eliminate the possibility of any foreign matter going through with the oil into the bearings will you please arrange to make pipes to house a Phantom III type of Tecalemit pressure filter in the main feed pipe from the pump to the bearings. This is only necessary to be fitted as a temporary measure while the chassis and unit are being 'run in', after which it is removed. Rm{William Robotham - Chief Engineer}/Swdl.{Len H. Swindell} | ||
