Lp.{Mr Lappin} has a friend who owns a 4¼ litre Bentley, and who is complaining bitterly of detonations. The car in a decarbonised condition apparently detonates on Ethyl fuel. We suspect that this is due to some defect in the governor. We should be glad if you could investigate this case, and see if you can put the matter right.(See Lp{Mr Lappin} about it) Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} Jorgensen made OK 6/10/36 | ||
