| (2). J.{Mr Johnson W.M.} for R.{Sir Henry Royce} 9.3.15. Pye/P9215. Since writing about 12 ED{J. L. Edwards} I have received another instruction sheet, that 6 IB another car is to be treated in the same way. Would you kindly let me know if you are in agreement with me in this matter, or do you think we should make a special design to suit their requirements. By.{R.W. Bailey - Chief Engineer} | ||
