| W/P - Sr. 1245 Rm{William Robotham - Chief Engineer}/Swdl.{Len H. Swindell}22/JH.6.7.37. Paris-Trials Car ( Bentley). Regarding the new trials car B-35-KU which is now on production test, we should like this car to be run with "Duckham adcoids" added to the fuel when you take it over. Duckhams own 3½ litre Bentley was run with these "adcoids" and on inspection after 38,000 miles was found to be in very good condition. The actual cylinder bore wear was as good as the best we have previously measured. Wewwill write to Duckham's for details with regard to arrangements for supplying you with "adcoids", also information on their use. Rm{William Robotham - Chief Engineer}/L.H.Swindall. | ||
