C. to Wor.{Arthur Wormald - General Works Manager} C. to By.{R.W. Bailey - Chief Engineer} ORIGINAL E2/M10.1.22. X4305 / X4390 40/50 CHASSIS. X.4387 EXHAUST HEATED THROTTLE & PILOT JET. In reply to your memos. Hs{Lord Ernest Hives - Chair}3/LG28.12.21. and Hs{Lord Ernest Hives - Chair}5/LG 29.12.21., just to hand. I will look into the point in connection with using an elbow extending into the float chamber for the petrol connection. There seems no objection to making the exhaust feed connection to the throttle at an angle. We endeavoured to put it in the best position for tightening up but there is no doubt that this has to be determined on the chassis. It also seems good to get the ejector effect mentioned with the return pipe. With regard to the lettering on the indicator plate for the instrument board this was held up pending a decision as to whether the control connection for shutting the main throttle was to be used or not. If you find it better not to use this inter-connected control, then the original lettering suggested for this plate will do, in which the operator is instructed to close the main throttle.
