| To DA.{Bernard Day - Chassis Design} from Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} c. to BY.{R.W. Bailey - Chief Engineer} Hs{Lord Ernest Hives - Chair}/Rm{William Robotham - Chief Engineer}7/LG14.1.29. 'SS{S. Smith}' CLUTCH. +7300 Although the SS.{S. Smith} clutches are now better, they still behave rather erratically. One cause appears to be the difficulty of getting lubrication on the large diameter sliding ball race. Is anything being done to prevent this sort of trouble? Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} | ||
