| Hs{Lord Ernest Hives - Chair}/Wst WST r/12a EP{G. Eric Platford - Chief Quality Engineer}/AGR30/MH.{M. Huckerby}20.6.34 re SPARKING PLUGS With reference to the last sentence of your Hs{Lord Ernest Hives - Chair}/Wst.7/MA.19.6.34, we do not agree that K.L.G. V7/1 plugs are suitable for use in Kestrel S. engines operating at the new rating of 2350 normal R.P.M. and using + 3 lbs. boost for take off. We suggest that Lodge A2/2 plugs should also be used for these engines. EP{G. Eric Platford - Chief Quality Engineer}/AGR | ||
