| G.W. Hancock, Esq., Hotel de France, Chateauroux(French test region), Indre, France. +350 Hs {Lord Ernest Hives - Chair} /Les.17/KW.12.9.35. Spectre(Codename for Phantom III) Steering Locks. Although your turning circles are better than Ph.II, which is left lock 50 ft. 9 ins., and right lock 55 ft. 7 ins., they are inferior to Spectre(Codename for Phantom III) I and the final Spectre(Codename for Phantom III). The final Spectre(Codename for Phantom III) should have a turning circle of 45 ft. in each direction. Spectre(Codename for Phantom III) I has an even smaller turning circle. The trouble of the turning circle getting larger has come about by the raising of the yoke pieces. For the latest yoke piece the wheel steering lever has been altered in shape.
