| BY/CS c. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} +8050 BY4/G.22.1.30. 40/50 HP. CHASSIS - EXTRA CYLINDER LUBRICATION. The Experimental Department inform me that the main oil supply pipe for the above is quite inadequate, and we must double or treble the area of the main supply pipe originally arranged for this service. Look into this matter and see what is the largest pipe we can get in. I would try for 7/16" or even 1/2" diameter if this can be arranged for. BY.{R.W. Bailey - Chief Engineer} | ||
