Coverley - Production Engineer} Rm{William Robotham - Chief Engineer}17/R.18.12.36. P.III ROAD SPRINGS. We agree that the outlook towards rubber spring shackles is now entirely different to what it was six months ago. The wave of customers' complaints regarding tyre noise has not materialised, even though the cars which have already been produced did not have the rubber between the springs and the axle. We have crystalised our views on the loss of control on the rubber shackles, it is worse than we supposed. We do not think at the moment, therefore, that anyone is justified in saying it is unwise to produce cars with the small spring eye if by so doing scrap can be avoided.
