| Rm{William Robotham - Chief Engineer}/PJH.9/JH. -2- 22nd. January, 1938. Our production people have received 4 steering rollers, your N.2790, which on inspection appear to have no preload and to be somewhat soft. We will be writing further on this subject but would suggest that you check the hardness of any further rollers you are now making. Yours faithfully, FOR ROLLS-ROYCE LTD. | ||
