| To RHC.{R. H. Coverley - Production Engineer} Hs{Lord Ernest Hives - Chair}/Gry.{Shadwell Grylls}19/KW.15.5.35. 4328 SpectreCodename for Phantom III Gear Lever. We want to try a change speed bracket in aluminium instead of the present steel construction. Could you use a complete existing assembly as a pattern, and let us have a casting for trial quickly ? We think a casting might be less resonant than the steel construction, which we have proved amplifies considerably gear noise.
