Hi Drew
Go to the following site
http://www.naa.gov.au/
Left click on “record search” on right,
Then right click on search now as a guest
Then left click on “basic search” which should appear towards the top.
Then in keywords type Ronald Hubert Cox then click search.
This will bring up a screen and on the right under the heading “Digitised Item” click on the little book two rows down. This will bring up 33 pages of information, which may be of interest
Kind regards
Ross
