" " Ck.{Mr Clark} X.3873. RE "BUZZARD" AND "VULTURE" REAR AXLE GEAR RATIOS. E2/G29.3.20. 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".
