| X1371 To DY.{F R Danby} from E.{Mr Elliott - Chief Engineer} E.12/HP.3.5.33. c. Hs.{Lord Ernest Hives - Chair} re Peregrine Undersheets. -------------------- Referring to LeC.3392 in connection with the above, this requires that there shall be no cooling ribs on the sump at the point where the undersheets fit closely round it near the flywheel case, and this modification is shown on LeC.3385, not yet issued. LeC.3385 is held up at the moment until the oil cooler is tested, and we know what we want to do with regard to the oil system. E.{Mr Elliott - Chief Engineer} | ||
