| V4553a G.W. Hancock, Esq., Hotel de France, Chateauroux, Indre, France. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}5/KW.24.7.34. 4-B-IV. Thank you for your letter of the 22nd. We are most interested in the fact that increasing your crankshaft damper load cured that most objectionable period at 3750 r.p.m. We are surprised that the intermediate silencer has altered the boom as it should be no different to the one you already have except that it is in Staybrite to ensure that it will not scale when lagged. We really wanted to be sure that the mild steel expansion box would not stand up before we fitted the Staybrite. You will doubtless let us have your opinion on the mild steel in due course. The oil leak on to the offside rear brake is disconcerting because your car has all our latest improvements on it. We understand that your oil drain is to N.Sch.3785, a print of which is attached, and if this is so we should like to know where the restriction in allowing the oil to drain away occurs. We are sending out to you the axle with the increased transverse pivot lean which you ran on your last 10,000 miles test, in order that you can compare the steering with the two axles and come to some conclusion as to their respective merits. We are also sending out to you some low rating front springs which we originally got out for the Bentley. It will certainly be interesting to try these road springs on pave and at the same time see how they affect the selectivity of the steering. Personally we believe that they will very adversely affect the road holding of the car. You are also receiving a thin Harrison radiator. This saves 35 lbs. weight on the car and we should certainly like you to give it a thorough test to see how it compares with the standard radiator both for hill climbing and all out speeds.
