The bent keys could be straightened.
I'll post the same advice I gave of deskthority incase someone here won it:
It anyone here wins this, rock the keys to and fro to remove them. Not left and right. Some of the keys seem to have bent stems already but you can straighten them but do not try to straighten them with the key caps attached as you can break a key caps mount point! From the 4th picture it looks like the rubber contamination shield (Canadian made beam spring) will need to be removed which isn't that much of a project.
If it smells try putting it in the same container with ground coffee (pre-brewing).
