| To RHC.{R. H. Coverley - Production Engineer} x1033 Hs{Lord Ernest Hives - Chair}/Swdl.{Len H. Swindell}11/KW.7.4.36. Phantom III. Will you please carry out the modification of fitting the under and direct petrol feed to the three Stromberg duplex carburetters which you are bringing up to date. The petrol feed modification which you carried out on 32-EX has proved satisfactory, and we have altered the needle orifice to .179" diameter which calls for a special needle, three of which we can supply you with.
