Nice work on the USAAF 27th Bombardment Group, 91st Bombardment Squadron A-24, Garry, and good background info, Michael.
Here is an image of a 27th BG A-24 in Australia.

And the one in the National Museum of the USAF. The link takes you to the photo and a useful fact sheet on the A-24 in USAAF service. The fact sheet also contains links to USAAF operations in Java and Papua, where A-24s of the 91st and 8th Bombardment Squadrons served.
