| TO HS.{Lord Ernest Hives - Chair} FROM AJS. AJS1/M4.3.27. ORIGINAL X4633 X3159 NEW DEPARTURE TYPE THRUST BEARINGS. Some long time ago now when we instructed the New Departure type of propeller thrust bearing in place of one actually made by New Departure, we believe we asked for some comparative tests to be made between our own type bearing and the original. We should very much like to have the result of the tests made on the Hoffmann produced bearing compared with the New Departure already tested by you. AJS. Memo AJS 1/M21-12-26 ? L.E. 2349.
