| To RHC.{R. H. Coverley - Production Engineer} 4300 a Hs{Lord Ernest Hives - Chair}/Std.17/KW.5.9.35. SpectreCodename for Phantom III Fan. As a result of tests in France we do not think that the SpectreCodename for Phantom III fan gives sufficient cooling, and therefore we should like to send Hancock a large and more effective one to try. We propose to use a standard Phantom fan (i.e., set of blades and centre boss). Will you please have the necessary adapting parts detailed and made to fit a set of standard Phantom blades to a SpectreCodename for Phantom III fan hub. Hs{Lord Ernest Hives - Chair}/Std. | ||
