| Ron GRY{Shadwell Grylls} x341 To DY.{F R Danby} from HDY.{William Hardy} C.E.Hs.{Lord Ernest Hives - Chair} PHS. SECRET. HDY.{William Hardy}1/HP.13.3.35. Servo - SpectreCodename for Phantom III and Wraith. With regard to the reverse pull rod between the servo and the balance lever, the slot in this, as shown by us does not extend upwards enough to provide for all contingencies and we should be glad if you would lengthen it by .200 and .150 for the SpectreCodename for Phantom III and Wraith respectively.
