| To HPS. {Horace Percy Smith - Experimental Factory Mgr} c Wym {G. Harold Whyman - Experimental Manager} 621p Rm {William Robotham - Chief Engineer} /Std.18/JH.15.12.37 In view of the fact that the engine unit of 27.G.VI car is to be changed very shortly and as only one set of parts for 5 blade fan with .85 speed ratio is available at the moment for the old type Wraith engine, we wish you to fit this set of parts to 28.G.VI. in the garage and leave 27.G.VI with its present standard fan. As the 5 blade fan has not yet been fitted to 25.G.VI. this will involve a negligible amount of extra work. Rm {William Robotham - Chief Engineer} /Std. | ||
