You could probably remove those 2 rusty brackets and replate them separately. I am working on setting up a zinc plating kit, just waiting for the zinc. It does not use any harmful chemicals and could probably be accomplished on the dining room table (not advised - but possible). Though they may have been plated with another material, zinc would look better, preserve the surface and could be removed if desired.

I'll let you know how it comes out.

Nice cabinet.
