| To [Redacted] from Rm.{William Robotham - Chief Engineer} Copy to Rm{William Robotham - Chief Engineer}/CTS.{C. Trot Salt - Carburation} 1123 CYLINDER BORE WEAR. Here is a list of Experimental Cars in the bore wear of which we are particularly interested. Where available, we should like to know the oil consumption for the 1000 miles prior to each bore measurement. This, of course, also applies to the other cars of proprietory makes which we are running. When any modification is made to a car, which is likely to affect bore wear, we should like the fact to be noted on the chart. Rm.{William Robotham - Chief Engineer} | ||
