We have had an official enquiry regarding US Army air photography over New Britain (part of Papua New Guinea) in 1943.

The compilation notes for the 1:63,360 map of Cape Turner (part of New Britain) produced by SWPA
(map online at https://nla.gov.au/nla.obj-278246511/view)  says:

Compilation from tri-metrogon aerial photography
Missions:
 26Z Jan 1943
 71C, 83X  March 1943
 111X, 112X April 1943
 137X May 1943
by 8th Photo Squadron, 5th Air Force, US Army.

Where can we find copies of that photography (whether online or not)?  I presume someone in the US will have them?  Can anyone point me to a likely source?

Thank you!
