| 8 450c. SECRET. By.{R.W. Bailey - Chief Engineer} from Rm.{William Robotham - Chief Engineer} Rml/R.17.7.39. Light Flywheel 'Corniche'. We note you have cancelled the light flywheel on the 'Corniche'. There was no evidence on the car in France that this made rattles in the gearbox appreciably worse. We admit that on the old 25/30 a light flywheel did make rattles in the transmission worse, but this was a different rattle, it did not occur from rest, it did not occur on the pick-up, but it did occur on the over-run at 45 to 50 m.p.h. Our flywheels are much heavier than those on the corresponding American cars. Rm.{William Robotham - Chief Engineer} | ||
