Hardy - Chief Dev. Engineer}4/AP.5.5.37 39-EX. STEERING AND OIL FILTER. On the above chassis it is now not possible to withdraw completely the oil filter in the sump, owing to the side steering tube being inside the frame. Will you please make one filter to the attached Rm.{William Robotham - Chief Engineer}372 which can be tilted when partially withdrawn to clear the S.S. tube.
