| ) 1260. G/Rb.{R. Bowen} from Rm{William Robotham - Chief Engineer}/Std. Rm{William Robotham - Chief Engineer}/Std2/R.11.3.37. You recently gave us the cost saving of RR.Sch.1045 over the standard 25/30 H.P. fan. The Design Dept. have now issued a design for a cheaper fan for Wraith - LeC.5552. Will you please give us the relative costs of RR.Sch.1045 and LeC.5552. We do not wish to duplicate work on cheapening the fan in question, so wish to proceed with the cheaper of the two above schemes. Rm{William Robotham - Chief Engineer}/Std. | ||
