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(Aero Engine) 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 | ||
