HS{Lord Ernest Hives - Chair} 4-0 E2/M16.8.27. 17-8-27 X3942 X4569 X4230 In response to your memo HS{Lord Ernest Hives - Chair}/RM{William Robotham - Chief Engineer}4/LG11827., the actual design of the 20HP. moveable idler wheel has never yet been approved, although the principle is conceded, being the same as we used on the larger engine. R.{Sir Henry Royce} has decided that this alteration will be dealt with when we modify the engine in other respects, so as to make a clean sweep of the whole job. E.{Mr Elliott - Chief Engineer} | ||
