| PRIVATE 16000. W/S In c. Hs{Lord Ernest Hives - Chair}/Wst EP{G. Eric Platford - Chief Quality Engineer}6/MH.{M. Huckerby}19.8.35 re SPARKING PLUGS ----------------- With further reference to our memo EP{G. Eric Platford - Chief Quality Engineer}12/MH.{M. Huckerby}17.8.35, and in regard to the penultimate paragraph. We should have made it clear that it is quite understood that D.T.D.230 fuel is only required in connection with the Kestrel X.engines when running full rated. This type of engine are all being turned out derated at present - presumably because of D.T.D.230 fuel not being available. EP{G. Eric Platford - Chief Quality Engineer} | ||
