Could those fleecy vests have come from the Russians ?
Anyways, there's NSW based photographic studios who passed their glass plates to the Mitchell Library in Sydney, and that those collections include AIF men photographed at the Liverpool camp (a training camp, southwest of Sydney NSW), BEFORE they were marched out, ie photographed BEFORE they left for the Western Front.
The Mitchell may also be in need of funding, as many of those plates have not yet been indexed .... but I feel sure that there's every likelyhood of finding good clear photos of the AIF faces to compare with those 3000 glass plates. Also, I understand that there's many glass plates stores at the AWM .... the main problem seems to be that there's NO NAMES recorded on individual plates.
Cheers, JM
