My guess is that there's a whole lot more value in that collection than some here may realize. I would seek out a knowledgeable 2-rail enthusiast (or two) who is/are not personally interested in buying the items to help evaluate their condition and worth. It may be hard to find such individuals, but it likely will be worth the effort.
The first step would be to separate the items from the layout; dust them off if necessary; and box them in their original boxes, if available.
An alternative would be to do the above and then approach an established auction house to see if they might be interested.
