E.{Mr Elliott - Chief Engineer} Hs.{Lord Ernest Hives - Chair} Da.{Bernard Day - Chassis Design} RHG. SpectreCodename for Phantom III and Wraith Gearboxes. We should like advantage to be taken of the isolation from engine vibration to reduce the thickness of the gear change lever from the present .350 to .300. This will help the sheet metal gate which has hardly sufficient strength in the prongs as it is. The change levers for the two cars can probably be identical and as the side travel in the gate is 1" for both the prongs will be of equal width in both in this case. HDY.{William Hardy} | ||
