She's probably contacted museums already and they've probably either told her that none of the equipment she has is of historical significance or that they'd love it but they don't really have a budget for acquiring stuff. There is somewhat of a surplus of old machine shop (basically what this business was) equipment. People retire, sell most of their stuff to other shops or individuals and keep a few of their most versatile machines for themselves (and their kids then sell or scrap them). Stuff doesn't usually get scrapped until it's a) totally clapped out or b) inherited by someone wealthy enough that they're not gonna bother selling old machines for a grand or two and would rather just call a scrapper to clean everything out. Also, the larger size machines that most production shops like this aren't worth much because the market is basically limited to other shops and a few industrious individuals and other shops already have equipment (and if they don't they're rarely buying old stuff).
