| BY.{R.W. Bailey - Chief Engineer} FROM DA.{Bernard Day - Chassis Design} X5310. DAL/M.11.1.32. Copy to HS.{Lord Ernest Hives - Chair} 25HP, S.M. GEARBOX. With the investigation we carried out on this box taken from 18-G-4. on Friday last we believe you have all the information from us that you require to proceed into production. The spigot bearing with a plain bush we understand to be that which we approved in Derby, with the qualification that we expect it to be demonstrated that the lubrication by holes drilled in to the bottoms of the teeth will work.
