Having now reread Ian Pfennigwerth’s “Man of Intelligence” and gone through various files at the NAA, I now have slightly more solid dates framing what Captain Nave was doing in 1949.
Having started work in the South Australian Railways (where his father Thomas worked), Eric Nave signed up for the Royal Australian Navy in 1917. He stayed there until 1930, when he was moved to the Royal Navy.
However, Nave’s RN personnel file is not only fairly brief (he was cheerful and intelligent), but only runs to 1948.
A large proportion of the papers in his NAA ASIO file relate to his pension, because his Royal Navy pension was not transferable to his wife. Because the Naves had four children, this issue required a fair bit of administrative attention. Redactions are merely senior officers’ names.
I incidentally found out that Nave owned a Holden sedan, and that his parents lived at 5b Arlington Terrace, Allenby Gardens, Adelaide.
Captain Nave’s 1949 Timeline
From the papers in the files, we can say definitively that Captain Nave: [page numbers from the ASIO file NAA: A6119, 3576]
* finished formal work with the RN in March 1949 (p.80)
* was allocated to the Terror “18.3.49 for dispersal” (Navy service record)
* had 160 days of untaken / carried over holiday (Pfennigwerth), though the Navy service record says “48 days N.S.L. 28 days E.O.W.L. 56 days release + RAN F.S.L.”
* was courted by ASIO as early as 13th May 1949 (p.87)
* officially retired on 22nd August 1949 (when his pension started) (pp.30-31)
* started with ASIO on 20th October 1949 (pp.30-31)
All of which means that Adelaide-born-and-bred Captain Nave was still (technically) in the Royal Navy in July 1949, when the Adelaide newspapers reported that a “local Navy decoder” was having a look at the Rubaiyat.
Are any of his children still alive?
