| To RHC.{R. H. Coverley - Production Engineer} x7962 HS{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}12/KW.18.7.34. Pipes on Hall's Car. Hall mentioned that he has had so many broken copper pipes on his various racing cars that he has recently made it a practice to have them all annealed within a reasonable period of the race. Whilst we have had no experience whatever with broken oil pipes on any of our cars we do not see that any harm can be done by annealing these pipes. (Scale?) [Handwritten note below] Rm{William Robotham - Chief Engineer} Petrol Pipes - important oil Pipes have been replaced. Therefore should be alright.
