| To HPS. {Horace Percy Smith - Experimental Factory Mgr} from Rm {William Robotham - Chief Engineer} /AFM. {Anthony F. Martindale} c. Rm {William Robotham - Chief Engineer} /wym. {G. Harold Whyman - Experimental Manager} 606 Rm {William Robotham - Chief Engineer} /AFM. {Anthony F. Martindale} 2/AP.2.8.37 WRAITH BRAKES 24.0.V1. The brakes on this car are obsolete and require modification. Will you please alter the Servo from LOP.GW.1068 to LOP.GW.1412. This means a new pair of cams and a new shaft. Will you please fit a plate lever, Rm. {William Robotham - Chief Engineer} 405. to the front equalizer. The brake drums have not been heat treated and they are crackling. The drums should be heat treated and new liners fitted having the correct interference. As this is a long job we would prefer to have a new set of drums fitted while it is being done. If it is possible to borrow the servo built up for the next Wraith while the new shaft and cams are being machined, we should like this to be fitted.
