| To D.A. from E.{Mr Elliott - Chief Engineer} Copy to C.J. BN{W.O. Bentley / Mr Barrington} (crossed out) HS{Lord Ernest Hives - Chair} (crossed out) X.3832 CK{Mr Clark} (crossed out) X.3843 ORIGINAL RE "BUZZARD" AND "VULTURE" REAR AXLE GEAR RATIOS. Information has already been sent that the back axle ratio of the "Vulture" should be 4.75 to 1. Would you kindly note that this ratio for the "Buzzard" should be 4.5 to 1 on account of the larger displacement of the "Buzzard" engine as compared with the "Vulture".
