Martindale} Rm{William Robotham - Chief Engineer}/AFM{Anthony F. Martindale}6/R.8.9.37. BENTLEY III YOKE. Will you please have two pairs of the above forged in 1% Chrome Steel (instead of S/NCR) and one pair of these fitted to the bump chassis. The latest yokes are very heavy and stiff, and, therefore, costly in S/NCR: the remainder of the sus-pension levers are made in cast steel, and are satisfactory. Roy{Sir Henry Royce}/Les.{Ivan A. Leslie} is ordering the steel. Rm{William Robotham - Chief Engineer}/AFM.{Anthony F. Martindale} | ||
