Robert,
I have more information on the JTD and a number of their men (Gillespie, Scott, Riordan, Goddard) in a daring, three week rescue in Dutch New Guinea in August 1944. On this rescue I wrote the book KAIS (https://www.amazon.com.au/KAIS-daring-rescue-swamps-Guinea-ebook/dp/B08643X9NJ/ref=sr_1_1?dchild=1&keywords=Kais&qid=1596743217&sr=8-1) and have been able to find the children of those four men.
I haven’t been able to find their records, neither with the Australian Army, nor with the USAAF (5th or 13th AF) yet. As they were attached to the Americans, they must probably have reported to them.
The picture was taken on 19 August 1944 after the succesfull rescue of the crew of a US B-25H of 418 NFS? They stand centre in front of the palm tree and far legt (US cavalry hat). Captain William Gillespie of the JTD is on the right (slouch hat) and far right the Dutch officer in command, Lt Louis Rapmund.
