I truly think this one will be difficult to save as a whole. You should consider cutting it into smaller pieces so the undamaged sections can be used as table runners or toppers, dresser toppers, etc.
Unfortunately there is so much damage to this one I would advise against trying to save it. Just saving portions of it will probably have to do.
It's a beautiful quilt, and I think you should do as above to save as much as possible.
