Help finding resources for a collection of older cameras

I have a friend whose husband has a box of older camera. He has no use for them at this time, and would like to find sources to either sell them, or donate to a worthy cause. Unfortunately I could offer very little help, but I told her that I had access to the best resource in the state and would inquire on her behalf.

Do you have any sources to suggest, or do any of you collect older cameras? Do you know of anyone at UNM who may have a resource?

Thanks so much!
