| 1235 S/W To Rm.{William Robotham - Chief Engineer} from Sg.{Arthur F. Sidgreaves - MD} Duckham's Oils. Sg{Arthur F. Sidgreaves - MD}2/E25.11.36 Referring to the copy of letter sent you yesterday I should like to have your comments on this. I was very much interested to see what he said because of our recommendation to people re P.III's and because I have begun to use it myself on GLG-5. I notice a very big difference in ease of starting. Sg.{Arthur F. Sidgreaves - MD} | ||
