Silly Saturday!!!

It was on the News tonight that a locker room key from The Titanic sold today for £85,000
I'm very hopeful that our key pictured here will sell for a similar amount.
The only problem is that I have no idea what it is the key for.
But then again, I don't suppose the £85,000 key will unlock anything!!!!!!
( I think the dish is probably worth another £16,500)
