| G.W. Hancock, Esq., Hotel de France, Chateauroux, Indre, France. +350 Hs{Lord Ernest Hives - Chair}/Les.17/KW.12.9.35. SpectreCodename 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 SpectreCodename for Phantom III I and the final SpectreCodename for Phantom III. The final SpectreCodename for Phantom III should have a turning circle of 45 ft. in each direction. SpectreCodename 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.
