| 1097 Ev.{Ivan Evernden - coachwork} from Rm.{William Robotham - Chief Engineer} cc. Rm{William Robotham - Chief Engineer}/GB. Rm{William Robotham - Chief Engineer}/HH. Rm{William Robotham - Chief Engineer}/FJH.{Fred J. Hardy - Chief Dev. Engineer} [Signature] Rm.{William Robotham - Chief Engineer}6/ML.20.10.40. The Vauxhall, when driven fast, does 28 m.p.g. It weighs 18 cwts. The Myth will weigh 22 cwts. If we do 25 m.p.g. and have one gallon reserve, we shall only have an exffective driving range between fill-ups, of 150 miles. One disadvantage of continually filling up is that it is inclined to give the owner the impression that his consumption is poor. I think we should have an 8-gallon tank on the Myth.
