The papers comprises Elkin's midshipman's journal, 1921 to 1923, his summaries and reports on Invergordon, 1931, and a later report written in 1967 for Captain Stephen Roskill's (1903- ) use in his history on Naval Policy between the Wars (London, 1968) as well as Elkin's wartime 'Line' books. These include accounts (as well as his official report, 1947) of his escape from St Valery, and of the proceedings for the surrender of the German squadron at Copenhagen. The draft of Elkin's reminiscences is closed to readers, by Admiralty direction, until 2004 A.D. The remainder of this group consists of arrangements for ceremonial Royal occasions, 1948 to 1951, and a selection of sea shanties, arranged for orchestra. The papers also include Len Wincott's book Invergordon mutineer (London, 1974) and the publicity given to his visit to England, also in that year.
