| To RHC.{R. H. Coverley - Production Engineer} X337 Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}7/KW.6.5.36. We have had such a lot of trouble with the Ph.III propellor shafts that we should like to dynamically balance them. The cage in which the Peregrine shafts were balanced is available but requires lengthening to suit Ph.III shafts. Will you please modify it as soon as possible.
