| Unior RHC.{R. H. Coverley - Production Engineer} from Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}11/KT.5.4.33. PEREGRINE UNIT NO.5. We find that the rings to Hs.{Lord Ernest Hives - Chair}945 and Hs.{Lord Ernest Hives - Chair}949 fitted to Per.3 to improve oil consumption appear to be effective. We should therefore like to confirm the results on the test bed, Per.5 unit being available on which an oil consumption has already been taken. Will you therefore please fit rings to Hs.{Lord Ernest Hives - Chair}945 and Hs.{Lord Ernest Hives - Chair}949 to this unit. At the same time will you please fit the camshaft to Hs.{Lord Ernest Hives - Chair}970, 111° - Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}1/KT.24.3.33.
