X.4230 X.4569 X.3942 In response to your memo. Hs{Lord Ernest Hives - Chair}/Rn{Mr Robinson}4/LG11.8.27., the actual design of the 20 HP. 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 ve 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} | ||
