| Rm{William Robotham - Chief Engineer}/IMW{Ivan M. Waller - Head of Chateauroux} (Chateauroux). 600a Rm{William Robotham - Chief Engineer}4/R.26.2.38. Thank you for your various reports. Do not harp too much on servo jaggers. Sg.{Arthur F. Sidgreaves - MD} has already got alarmed about them, and my reply has been that if we cannot get rid of servo jaggers before the Wraith goes into production, then the whole of the staff should take up agriculture. When Martindale has got a solution he is coming out. Rm.{William Robotham - Chief Engineer} | ||
