| Rm{William Robotham - Chief Engineer}/MHR.{M. H. Rigby} from Rm.{William Robotham - Chief Engineer} 1294 Rm.{William Robotham - Chief Engineer}5/ML.17.12.40. WATER EXCLUSION FROM THE SERVO. With reference to your Memo. Rm{William Robotham - Chief Engineer}/MHR.{M. H. Rigby}6/ET.13.12.40. I still feel that a rubber seal will always be most effective against water penetration, provided it could be made to stand up. I therefore think that you should try this once again before you abandon it. Rm.{William Robotham - Chief Engineer} | ||
