| To E.{Mr Elliott - Chief Engineer} From Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson} c. to By.{R.W. Bailey - Chief Engineer} c. to Wor.{Arthur Wormald - General Works Manager} Y 5050. Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson}6/MJ.20.4.32. J.{Mr Johnson W.M.} 3. CYLINDER HEAD. We have found on the test bed that if we block up the water holes as shewn in Sketch V.1343, the overheating of the back cylinders is largely overcome. With this alteration there is a difference of something less than 20 between cylinders 1 and 6. This compares favourably with our existing 'China' unit.
