| To RHC.{R. H. Coverley - Production Engineer} X328 Hs{Lord Ernest Hives - Chair}/Gry.{Shadwell Grylls}13/KW.11.2.36. Phantom III Gearboxes. With regard to the gearbox you are building in order to test the Design Dept. isolated change speed and also the taper fixing of the continuous gears, we should like this box to have the Cadillac type of gears as these have never been tested on the dynamometer. One test will then suffice to test both the gears and the fixing. Hs{Lord Ernest Hives - Chair}/Gry.{Shadwell Grylls} | ||
