Firstly, this thread is for listing known fakes, not for questions/enquiries, as indicated in the title of the thread.
Secondly, a quick glance at the collection indicates to me that there are a number of "parts box watches" where various dials/cases/movements have been put together from whatever left over spares the Pommies left behind. As such their collectibility as military watches is, to be blunt, Zero.
Should you wish to list one in a new thread for an assessment, then by all means do that, but I suspect that they will all be of the same style.
They are OK if you aren't a serious military collector, and some collectors may buy one because of the dial/hands/case or movement, but much better photos would be needed.
