On auction is a nice copy of a WW2 RAF "AP 1081 R.A.F. Pocket Book 1937". This book was originally published in 1937 (3rd edition) and reprinted in July 1942 in India (reprint of the 1939 amended reprint published in the UK).

The RAF Pocket Book is in many ways the RAF equivalent of "Staff Duties in the Field", issued to ground forces. It covers administration, discipline and signals. Of particular importance to airmen it also deals with air navigation, meteorology, airmanship and many other important topics, including liaison with the Navy and the Army. It also covers explosives and weapons in 17 chapters which give a very detailed picture of how the RAF thought and worked in the early years of the Second World War.
