| X4264 Mr Booth from BY. {R.W. Bailey - Chief Engineer} c. Hs. {Lord Ernest Hives - Chair} X4264 BY2-P6.10.21. GOSHAWK(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)) 11. STEERING COLUMN. I believe we have recently reduced the clearance very considerably on the 40/50 Steering Column in the top bearing for the controls. Please confirm that this has actually been done, and note that on Goshawk(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)) 11, exactly the same clearance must be maintained as on the improved 40/50. Kindly arrange to alter any drawings which have been issued which are not in accordance with this instruction. BY. {R.W. Bailey - Chief Engineer} | ||
