removing a sink overflow

[JohnD]

I have a stainless klitchen sink where the overflow has been leaking, I want to get it off and fit a new one.

I am used to baths where the grille inside the bath is screwed into a socket on the end of the flexi hose, but this one doesn't feel like it unscrews. It used to have a bolt going into it for the plug chain, but this went rusty and broke off.

As the overflow is up behiond the sink, inside a tight cabinet, I can't see how it is fixed.

What is usual, or, what short-cuts for getting the old one off? I don't mind damaging it.

If the screw broke off in antiquity there's a good chance that the only things holding the overflow on to the outside of the bowl are cack and maybe the stub of the bolt. Give it a prod if you're feeling brave , but bear in mind that you could break the seal.
