| (x+037). To Hs.{Lord Ernest Hives - Chair} from Hs{Lord Ernest Hives - Chair}/GWH.{George W. Hancock - Head Chateauroux} c.c. By.{R.W. Bailey - Chief Engineer} [Text is crossed out] Hs{Lord Ernest Hives - Chair}/GWH{George W. Hancock - Head Chateauroux}2/ADL.10.30. We have tested out two Autokleen filters with the spring loaded gland. In one case there is no improvement in the oil leaking from the gland, the other gland so far is showing no leak but it has not been in use as long as the first which is leaking. We cannot detect any difference in the fitting up of the two glands. Hs{Lord Ernest Hives - Chair}/GWH.{George W. Hancock - Head Chateauroux} | ||
