Requiring only an aerial and an earth and no power, this set will work forever.
The mahogany cabinet is original. The detector did need work, a new piece of Galena and a "Cats Whisker" kindly supplied by Gerry Wells. I have now obtained a pair of BTH headphones to go with it. The set remains working permanently.
