| 308 Rm{William Robotham - Chief Engineer}/GR.{George Ratcliffe} from Rm.{William Robotham - Chief Engineer} Rm{William Robotham - Chief Engineer}5/R.18.1.38. We understand that the weaker jets in the P.III carburetter which have now been standardised, necessitate the carburetters going back to the Zenith Co. for fitting. We should like to know why this is necessary. Rm.{William Robotham - Chief Engineer} | ||
