You'd be surprised what people doing period-correct restorations will want - even though these are in "horrible shape" they may still be good for parts!
We've restored several trailers and always were in need of donors for parts...good luck! I've even seen where folks take the door of a vintage fridge and use it added onto a new fridge to "look" vintage even if it isn't.
Thank you for offering them up and not dragging them off to a landfill!
