P.III. GEARBOX. As discussed with you, we want to alter slightly our arrangements about these gearboxes. We no longer wish to fit an overdrive gearbox to 37-IX, and will you, therefore, please send to the Repair Department box No.12.HS.{Lord Ernest Hives - Chair} and a suitable rear crossmember, new propeller shaft and rear axle flange. Box.No.17, when it has been re-assembled after seizure of the overdrive bushes, should be fitted to 32-EX. Rm{William Robotham - Chief Engineer}/Gry.{Shadwell Grylls} | ||
