I don't know why you wish to get rid of this fantastic collection, ABN RFN, but have you considered contacting the RCAF museum in Trenton? I think they would love such an addition to their collection.
In my (albeit limited) experience, when a complete collection of models, like this one, is given to the military, two things happen:
First, the collection is usually given the name of the collector/maker who made the donation, so the person's name goes on being recognized (for instance, the Gilmour collection at the museum of HMCS DONNACONA); and,
Second, an estimate of the collection value is made and a tax credit for donation to the crown can be issued if liked.
