| Rm{William Robotham - Chief Engineer}/HH. from Rm.{William Robotham - Chief Engineer} Patterns Rm.{William Robotham - Chief Engineer}2/ML.9.5.41. 1246 We are now about to get the universal pattern completed from which we shall make 3 1/4, 3 1/2, 3 3/4, and 75 mm. bore 6-cylinder engines. Will you please see that Rm{William Robotham - Chief Engineer}/CTS{C. Trot Salt - Carburation} has a copy of any modifications which have been incorporated on these engines since the original drawings were issued, in order that the pattern may represent the latest information available.
