Sidgreaves - MD} re WXA-1. Sg{Arthur F. Sidgreaves - MD}7/E14.4.38 Copy to Hs.{Lord Ernest Hives - Chair} Ld. [Initialled 'Rm{William Robotham - Chief Engineer}'] Kennett found that the engine was missing under certain conditions. He, therefore, examined the plugs, found they were in rather a dirty state and one at least of them very oily so he fitted a new set and returned them to LA.{L. A. Archer} This was done at an approximate total distance run of 2500 miles. I should like to have a report in due course because, as you know, the car has been used under the conditions in which a normal customer would use it. Sg.{Arthur F. Sidgreaves - MD} No signs of misfire in the car. Rm{William Robotham - Chief Engineer}/ED{J. L. Edwards} Tested in a wraith by whyman. | ||
