| 1020a Dennis Section To HPS.{Horace Percy Smith - Experimental Factory Mgr} from Rm{William Robotham - Chief Engineer}/Mths.{Reg Matthews} Rm{William Robotham - Chief Engineer}/Mths.{Reg Matthews}8/MH.{M. Huckerby}23.11.37. DENNIS BEARINGS. With reference to our memo Rm{William Robotham - Chief Engineer}/Mths.{Reg Matthews}5/MH.{M. Huckerby}18.11.37 will you please produce these bearings from billets in the normal way and not by the centrifugal process as instructed in the above memo. The results of the tests on B.9 Unit indicate that we have still some further work to do with bearings produced by the centrifugal method.
