| /231 EXPERIMENTAL DEPARTMENT. Rm{William Robotham - Chief Engineer}/IMW.{Ivan M. Waller - Head of Chateauroux}8/JH. 5th. May, 1939. C.C. Wakefield Ltd., Research Dept., Hayes, MIDDLESEX. For the attention of E.A. Evans. Dear Sirs, We are sending you a sample, 1 gallon about, of Castrolite which has been used in one of our experimental cars. We should be very glad if you could let us know if you pass this off as alright, or if it has lost any of its lubricating properties or is in any way unfit for further use. We should like to know exactly how it differs on analysis from new oil. Yours faithfully, FOR ROLLS-ROYCE LTD. | ||
