| Hs {Lord Ernest Hives - Chair} X7941. To Hs. {Lord Ernest Hives - Chair} from Sg. {Arthur F. Sidgreaves - MD} re 19-EX. Sg {Arthur F. Sidgreaves - MD} 1/E10.5.32 Copy to Wcr. The reports on this car indicate that the engine pre-ignites very badly if driven hard, which trouble brings several others in its train. One imagines that the further increase in compression ratio is the cause of this. It is of course quite evident that we could not offer a car for sale with this characteristic, and such being the case, it seems to me that no good purpose could be served by continuing the 10,000 mile test and that the best thing to do is to recall the car in order to make whatever alterations are necessary to overcome this defect. There is also the question of the synchromesh and the trouble with the gears coming out. A memo. from E. {Mr Elliott - Chief Engineer} received this morning, E1/HP9.5.32, suggests that there is insufficient clearance between certain parts on this particular gearbox. Here again the remarks as above more or less apply. I should be glad to hear by return as to what action has been taken. Sg. {Arthur F. Sidgreaves - MD} | ||
