Coverley - Production Engineer} Rm{William Robotham - Chief Engineer}4/R.23.11.37. A.C.7 BEARINGS. In view of the fact that we are for the time being committed to fit white metal rear main bearings, the rest being in A.C.7., the attached report from Hancock shows that we ought to be fairly free of service troubles with this combination.
