| To Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} from E.{Mr Elliott - Chief Engineer} SECRET. E.3/HP.6.6.35. c. Hs{Lord Ernest Hives - Chair}/LFS. SpectreCodename for Phantom III Engine Mounting. In connection with the SpectreCodename for Phantom III engine mounting, we notice that you are still running engine rubbers with the old small washer above the rubber, and no other support, with the consequence that there is considerable distortion, and the load carrying capacity is thereby reduced. We instructed a modification to overcome this trouble in October last year - LeC.4117, the modification merely consisting of inserting a large supporting washer above the rubber. We should be glad to know if you have tried this and with what results. E.{Mr Elliott - Chief Engineer} | ||
