| 1097 Rm.{William Robotham - Chief Engineer}S/ML. Messrs Vauxhall Motors Ltd., LUTON. Beds. For the attention of Mr. R.N.Gale. Dear Sirs, Thank you for your letter of the 16th. October. The Vauxhall 10 h.p. car we are using has been run on VIS. 20 oil. We have been using one of our own cars running in parallel with the Vauxhall. The mean rate of bore wear is rather less than 1/3 of the figures we sent you. Yours faithfully, for ROLLS ROYCE LTD., | ||
