| To DA.{Bernard Day - Chassis Design} from Hs{Lord Ernest Hives - Chair}/Rs.{Sir Henry Royce's Secretary} c. to HX. EP.{G. Eric Platford - Chief Quality Engineer} c. to HY.{Tom Haldenby - Plant Engineer} X5310 X5320 Hs{Lord Ernest Hives - Chair}/Rs{Sir Henry Royce's Secretary}/LGS.12.27. The Test Dept. have been troubled by a vibration of the change speed lever which coincides with the crankshaft periods of the car, greatly accentuating any roughness particularly at high revs. on 3rd. speed. Attached is a report by GWI. who has investigated the trouble. We recommend that the small rubber pellet should be adopted and applied retrospectively in cases of complaint.
