Coverley - Production Engineer} Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} Gry.{Shadwell Grylls} Please follow this up re SpectreCodename for Phantom III Front Engine Mounting. We send you herewith drawing:- LeC.4117 showing an experimental modification that we should like tried. We feel that the weight on the rubbers is too localised, and it is thought that by placing a large diameter washer on top of the rubber we shall get more rubber in contact with the foot as the load increases. Although the drawing calls for a new pot, this is not essential, as a washer can be inserted between the face of the pot and the underside of the engine arm. E/JNR.{Charles L.
