| W/P. (Strikethrough) To Sr/Va. from Rm{William Robotham - Chief Engineer}/AFM.{Anthony F. Martindale} (Strikethrough) C. Rlye (Strikethrough) c. Hd.{Mr Hayward/Mr Huddy} (Strikethrough) c. Rm{William Robotham - Chief Engineer}/GWH.{George W. Hancock - Head Chateauroux} W/K.{Mr Kilner} Rm{William Robotham - Chief Engineer}/AFM.{Anthony F. Martindale}3/MH.{M. Huckerby}20.10.38. RE SERVO - BENTLEY CHASSIS. In reply to your Sr/VA.4/HB.{C. E. Harcombe}18.10.38. The servo in question is no longer being made therefore the pins cannot easily be lengthened, although there appears to be room for a longer pin. Your other suggestion of opening the end of the bush with a taper reamer appears to be good and we think any servo that has to be pulled down should be so modified. when we have a drawing ready we will issue a Depot Sheet. We cannot understand a verbal statement made to Rm.{William Robotham - Chief Engineer} that the 20-25 H.P. splined servo linings give trouble due to fouling inside. So far as we are aware only the Phantom III and 'M' series Bentley have splined linings, and the latter can hardly be a service trouble yet. The Phantom III servo has plenty of clearance inside to allow for servo disc wear. If you will explain further what the trouble is we shall be glad to look into it.
