| To E.{Mr Elliott - Chief Engineer} L300 HS{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}10/KW. 25.4.35. SpectreCodename for Phantom III Controls. Referring to E.3/HP.17.4.35. We discussed the controls on the drive to Nottingham, and Sg.{Arthur F. Sidgreaves - MD} was particularly anxious that we should try a scheme where the length of lever is left as at present, and that the control box should be increased in diameter so that it comes close to the piston knobs. As the diameter is increased, the depth of the box should decrease, thereby eliminating the existing appearance of undue height. If you will let us have a sketch we will make this up for your inspection. HS{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} | ||
