| 664 S/W To Rm.{William Robotham - Chief Engineer} from Sg.{Arthur F. Sidgreaves - MD} re WMB11 SG{Arthur F. Sidgreaves - MD}3/E11739 The detonation to which I have referred is - perhaps not unnaturally - getting a little worse. I should like to get this seen to before the holiday and think perhaps the best way will be to put the engine back to standard. I propose, unless I hear from you to the contrary, to send the car up on Monday and presume you will not want it for more than 2 or 3 days. Sg.{Arthur F. Sidgreaves - MD} | ||
