Extender Ring for Halogen Oven (Belle Isle, LS10)

Can anyone make use of this halogen oven extender ring?

Over the years I’ve had 2 halogen ovens where unfortunately the tubes went in both of them & neither tube could be replaced so they couldn’t be repaired. It seems a shame to just throw this extender ring away when it is all intact. It has been used though & has been in storage, so it will need a good clean before use. Collection from LS10.
