| To Hs. {Lord Ernest Hives - Chair} from Rm {William Robotham - Chief Engineer} /GWH. {George W. Hancock - Head Chateauroux} c. Rm. {William Robotham - Chief Engineer} c. Rm {William Robotham - Chief Engineer} /Gry. {Shadwell Grylls} c. RHC. {R. H. Coverley - Production Engineer} 1113 Kingsbury. May 11th.1937 Bentley. 178.JD. {J. Draper - Frames} This car was sent up to Kingsbury from Lillie Hall, Evans having turned down the rear axle. I took the opportunity to try the car. There was a bad over-run period at 1600 revs. per min to 1400. As the axle warmed up it was more noticeable. The prop. damper load was from the feel of it standard setting. I understand Evans is sending this axle back to the works. Rm {William Robotham - Chief Engineer} /GWH. {George W. Hancock - Head Chateauroux} | ||
