| To By.{R.W. Bailey - Chief Engineer} c. to Da.{Bernard Day - Chassis Design} +350 Hs{Lord Ernest Hives - Chair}/FJH.{Fred J. Hardy - Chief Dev. Engineer}8/KW.12.7.35. SpectreCodename for Phantom III Steering. In addition to the various features which we have for test on the SpectreCodename for Phantom III steering, we wish to be able to try Timken Roller Bearings on the roller of the steering gear as shown on N.Sch.4489. The above scheme shows special bearings with the inner races splined internally. In order to obtain a quick trial of this feature, we suggest that standard races - A.4000 series in the Design Dept. Catalogue - should be used, and a sleeve fitted between the rockershaft pin and the races. Will you please detail the above scheme so that we can try it as soon as possible.
