| Y260 To RHC.{R. H. Coverley - Production Engineer} Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}11/KW.3.1.35. B-7 Unit ex Lappin's Car. Will you please rebuild this unit exactly as it is, replacing only those parts which are unfit to continue running. We propose to use this engine for a spare small bore test bed unit. As soon as we get our full quota of large bore units we shall probably scrap it. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} | ||
