| S/W. To Hs.{Lord Ernest Hives - Chair} from Lp.{Mr Lappin} Copy to Wor.{Arthur Wormald - General Works Manager} X728 Lp{Mr Lappin}4/LAM.13.4.33. Re: HALFORD - AUTOMATIC TAPPETS. With reference to Hs.{Lord Ernest Hives - Chair}9/KT.11.4.33., we have written to Major Halford asking him to send you particulars of his automatic tappets. If they are as successful as they claim on the 24 Cylinder Engine, it will be a very excellent talking point for the air-cooled supporters at the Air Ministry. Lp.{Mr Lappin} | ||
