| To DA{Bernard Day - Chassis Design}/EV.{Ivan Evernden - coachwork} from Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} X5830 Hs{Lord Ernest Hives - Chair}/Rm{William Robotham - Chief Engineer}6/LG31.8.28. FRONT WINGS - 12-G-4. X5390 The front wings of this car have no mud-lip on them. We do not know whether they were made like this with a specific object in view, but we have not altered them since no objection was raised by Mr. Royce. The fact remains however that they allow quantities of mud to blow off the edge of the wing on to the body and windscreen and we feel we ought to draw your attention to this point.
