| To E.{Mr Elliott - Chief Engineer} c. to E/Psn. c. to Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} +300a (W) Hs{Lord Ernest Hives - Chair}/GWH.{George W. Hancock - Head Chateauroux}30/KW.7.10.35. Phantom III. 31-EX. Reverse Throttle Carburetters - Lightened Throttle Spring. Re your memo. E/PSN.3/MN.4.10.35. Having made the link to your instructions and altered the levers to toggle as per instructions, we now obtain a load of 7 lbs. on the accelerator pedal for a third (approx.) of the opening. A load of 15 lbs. has to be exerted to keep the throttle fully opened. This load is too great. We are waiting for your further instructions to reduce this load.
