| 10HH J 1116 By.{R.W. Bailey - Chief Engineer} from Rm.{William Robotham - Chief Engineer} c. Da.{Bernard Day - Chassis Design} c. Da{Bernard Day - Chassis Design}/Jnr.{Charles L. Jenner} Rm{William Robotham - Chief Engineer}2/R.27.4.39. The suggestion that the spring drive takes out gear rattle on crankshaft periods and so apparently makes the damper more effective, is ingenious and remains to be proved on the road. The chain may not rattle so much since other people do not have spring drives. Rm.{William Robotham - Chief Engineer} | ||
