| 300 s/W. {Sales / Derby Works} c. to Rm. {William Robotham - Chief Engineer} re- 34-EX. Cx {Major Len W. Cox - Advertising Manager} 9/KW/21.12.36. W. are very anxious indeed to have very accurate records of the oil consumption of this car, particularly as it is one having special piston rings. Would you therefore keep a complete record of this and send it to Rm {William Robotham - Chief Engineer} on 15th of every month. Perhaps you would let me have a copy at the same time.
