GRY{Shadwell Grylls} See mc WHITE STAR LINE ON BOARD M.V. "BRITANNIC" Sunday Jan 7th. whether it was caused by the thrust on the splines as we previously suspected. SpectreCodename for Phantom III Suggest you get E.{Mr Elliott - Chief Engineer} to make sure that this clutch is as light as possible + has absolutely the minimum overhang because a flywheel period seems to be the one thing that may spoil a 12 cyl Engine. Most of the American 2/plate clutches do not seem as compact as they might be. Even with the fully balanced shaft there is Hs{Lord Ernest Hives - Chair} We ought to reach N.Y. tomorrow, Monday, shortly after noon. Re Bentley thrust race. If this is the same as on the 20/25 it seems inexplicable that it should have collapsed from torque in view of the fact that bottom gear is so much higher in the Bentley. I was wondering | ||
