| 361. S/W Rm{William Robotham - Chief Engineer}/Gry.{Shadwell Grylls} C3/C7.4.37 Re 3.AZ.170....Mr.Leonard. We have ascertained from Mr.Leonard that he has now covered 1,000 miles since the modification and has not moved a plug. He said the oil consumption was satisfactory but actually he had not taken a real test. He now proposes doing so during the next 1,000 miles he covers and will advise us of the result. This appears to be 'so far so good.' C. | ||
