| 1202 To TB/KNG. from Rm.{William Robotham - Chief Engineer} Rm.{William Robotham - Chief Engineer}8/SW.19.7.41. Thank you for your memo reference TB/KNG.1/JT.17.7.41., we note the castings you have made from RE.107 and RE.112. We are glad to hear that you do not think it is impossible to make D.13256/1 in iron, and we consider the preliminary experiment of taking a casting off the existing patterns, is well worth while. We shall await the results of your efforts with interest. Rm.{William Robotham - Chief Engineer} | ||
