| 1130/ Les/FS.{F. Steele} from Rm{William Robotham - Chief Engineer}/CTS.{C. Trot Salt - Carburation} Rm{William Robotham - Chief Engineer}/CTS.{C. Trot Salt - Carburation}3/JMS.24.7.40. Phantom III Filter. Re: your memo Les/FS.{F. Steele}10/B.19.7.40. We have the sample filter submitted and we cannot help you very much even now, because we have no facilities for flow testing same (as suggested in your previous memo) and the quality should be approved by the Inspection Dept. who turned down the first consignment. I am sorry if you are meeting with some delay in this matter, but your sample just received is the first one of its kind submitted to me for trial or opinion.
