| 1133 To Ev.{Ivan Evernden - coachwork} from Rm.{William Robotham - Chief Engineer} Rm.{William Robotham - Chief Engineer}1/MH.{M. Huckerby}27.10.39. You will note that I am continuing talking about the 2.1 litre 4-cylinder. Actually, of course, this is going to be made slightly less than 2 litres, but I am not changing the nomenclature until we are sure what size this is actually going to be.
