Hallam - Head Repairs} 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". We think this is interesting in that the Cadillac steering is definitely more immune from road shocks than the La {L. A. Archer} Salle steering at present fitted to the Spectre(Codename for Phantom III). Hs {Lord Ernest Hives - Chair} /Hm. {Capt. W. Hallam - Head Repairs} | ||
