Bailey - Chief Engineer} Hs{Lord Ernest Hives - Chair}/Rm{William Robotham - Chief Engineer}2/LG26.6.28. 40/50 CENTRALISED LUBRICATION. We believe that now we have a reasonable oil supply to all the points of the chassis. We have overcome the original difficulty we had with the distribution in the pivot system. The one remaining point that we have previously mentioned is the single Bijur drip plug filter being inadequate in area for the amount of oil passing to the pivot system. We have run 23 hrs. on the bump with the complete system - no pipes have so far failed or given other trouble. We did not have a failure during the 2500 miles running in France.
