| 1245. W/P. To Sr.VA. from Rm{William Robotham - Chief Engineer}/AFM.{Anthony F. Martindale} c. Hd.{Mr Hayward/Mr Huddy} c. Rm{William Robotham - Chief Engineer}/GWH.{George W. Hancock - Head Chateauroux} Rm{William Robotham - Chief Engineer}/AFM.{Anthony F. Martindale}3/MH.{M. Huckerby}31.10.38. SERVO - PHANTOM III CHASSIS. In reply to your VA.2/ET.25.10.38. The modification you propose to increase clear- on the servo was brought in on the 1st. car in 'D' series. We suggest that any servos suffering from this trouble should be machined to the latest drawing. To do this it would be advisable to have one or two spareservos in each depôt, and change the servos. There is no need for the cams to be changed, as these have to be removed to take the servo to pieces. Rm{William Robotham - Chief Engineer}/AFM.{Anthony F. Martindale} | ||
