Bailey - Chief Engineer} Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}4/KW.22.11.34. We have just received the following cable from Olley in response to our telegram asking him for details of the helix angle on the Cadillac steering :- "HELIX ANGLE SIX DEGREES 35 MINUTES AT CENTER".

Archer} Salle steering at present fitted to the SpectreCodename for Phantom III. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} | ||
