ACAC
I visited your list and even edited the dates for one of the lesser known airlines.
My initial thought was that it's a pity you are intending to limit the list to RPT as this will entail culling a lot of names and therefore (imho) reducing the usefulness of the list. As you have chosen the name "Australian Commercial Aviation Collection" you should be able to accommodate all operators without having to amend your constitution. Speaking of which, have you made provision for the preservation of donated items in the event (God forbid) that your organisation is wound up?
