| TB 1318 To Rm {William Robotham - Chief Engineer} /Mths. {Reg Matthews} from Rm {William Robotham - Chief Engineer} /Swdl. {Len H. Swindell} c. to Rm {William Robotham - Chief Engineer} /CTS. {C. Trot Salt - Carburation} Rm {William Robotham - Chief Engineer} /Swdl. {Len H. Swindell} 18/AP.9.12.36. PHANTOM III. Will you please carry out a test on the hot spot box, to determine whether the front inlet water pipe to the box can be deleted without affecting the temperature as registered by portable thermo couples on the external srface of the box at different points. The single pipe feed should be compared with existing doube pipe feed and if deletion of front pipes is successful then the 4 port head cango into Production with a single feed which saves weight and expense.
