| 6.66 + 424 To HPS.{Horace Percy Smith - Experimental Factory Mgr} c. to HPS{Horace Percy Smith - Experimental Factory Mgr}/RH.{R. Hollingworth} Rm{William Robotham - Chief Engineer}/Ed.{J. L. Edwards}6/JH.21.6.39. Fan for 30.G.VII. We observe that a standard Wraith fan has been fitted to the above engine unit for the above chassis instead of the modified fan as called for in Rm{William Robotham - Chief Engineer}/Ed.{J. L. Edwards}15/JH.12.6.39. We should be very glad therefore if you would carry out the necessary modification consisting of shortening the blades by 1.0" and checking the fan balance before the car goes away.
