Hs.{Lord Ernest Hives - Chair} Mr. RHC.{R. H. Coverley - Production Engineer} (Struck through) SpectreCodename for Phantom III Gearbox. N. Sch.4326 herewith shows 1st speed gears to give a higher ratio (.37) to help to overcome heavy operation when cold and to reduce stresses generally. If grinding cannot be done without delay we suggest that one set be put through unground. We are sending a print to RHC.{R. H. Coverley - Production Engineer} direct. N.Sch.4326 to BY.{R.W.
