| To Sg.{Arthur F. Sidgreaves - MD} from Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} c. to WoR.{Arthur Wormald - General Works Manager} x7960 Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}2/KW.2.2.35. Marles Type Steering on WoR{Arthur Wormald - General Works Manager}'s car. Replying to Sg.{Arthur F. Sidgreaves - MD}10/E.30.1.35. The steering on this car is of a lower ratio and we think a better compromise than the one on 21-G-IV. We are having the one on 21-G-IV converted and shall be in a better position to pass an opinion when we have two cars running about with the same steering.
