Six Production Wraith Cars. The above cars are to have aluminium brake drums and aluminium shoes with tipping shoes, and they will be built shortly. We understand the scheme OCD.39 shows aluminium shoes with tipping shoes which will satisfactorily fit inside aluminium drums, and that details of the shoes are available for RHC. {R. H. Coverley - Production Engineer} The scheme OCD.32 has been cancelled and replaced by OCD.152. It is important that these shoes should fit inside aluminium front drums as well as the latest iron drums, and that the details should be available at an early date. Will you please look into this matter. Rm {William Robotham - Chief Engineer} /AFM. {Anthony F. Martindale} | ||
