Bentley Rockers. In conjunction with running rockers direct on to a copper plated rocker shaft as requested in the memo Rm{William Robotham - Chief Engineer}/Sw d15/AP.4.2.37, will you also carry out the following and produce 1 set for trial. Standard rockers whitemetalled on the inside bore, then reamed to give the same clearance on the shaft as the present bronze bushes give. In order to obviate the necessity of special rocker forgings special spacing washers to be made. This also applies to the rockers which are to be run on the coppered shaft.
