| x350 To By.{R.W. Bailey - Chief Engineer} c. to Da.{Bernard Day - Chassis Design} Hs{Lord Ernest Hives - Chair}/FJH.{Fred J. Hardy - Chief Dev. Engineer}1/KW.10.10.35. Ph. III Steering. The steering of 31-EX (2nd 10,000 miles test car) is built up with a cam having 0.002 crowning of the track instead of 0.005 as previously. As the steering of this car is better than that of the demonstration cars, we want all future SpectreCodename for Phantom III cams to have the reduced crowning. If the cams for the 12 demonstration cars have not already been made we should like these to have 0.002 crown also. Hs{Lord Ernest Hives - Chair}/F.J.Hardy. | ||
