| 1235. Experimental Dept. Rm{William Robotham - Chief Engineer}/Swd.1.1/JH. 28th November, 1936. Messrs. Alexander Duckham & Co. Ltd., Duckham House, 16, & 18, Cannon Street, London.E.C.4. Dear Sirs, We thank you for the 3 barrels of oil NP1, NP2 and NP3, which we have received, will let you know the result of our tests as soon as they are completed. If you could supply us with viscosity curves of these oils ranging from 5ºC to 150ºC we should be grateful, as from these figures we can line up our tests with other makes of oils having similar viscosity. Yours faithfully, FOR ROLLS-ROYCE LTD. | ||
