By/NS.{Norman Scott} Rm{William Robotham - Chief Engineer}/FJH.{Fred J. Hardy - Chief Dev. Engineer}8/MR.23.1.39. B.V. STEERING. The cross and side steering tubes have recently been released for the first 50 chassis. We think that the tubes should be of nickel steel jumped up at the ends as we shall not have sufficient experience of the mild steel parallel bore tubes by the time the first production material is ordered.
