Herewith we send M.{Mr Moon / Mr Moore} sch. 3161. showing the arrangement of the oil pump and lubrication jet on the forward part of the above gearbox. The way shown of shaping the 2nd. motion shaft so as to lead the oil to the bearings at each end is somewhat experimental and some modification may be required as a result of trial.
