A guest on the Antiques Roadshow was left shocked when he discovered a "toolbox" that had been shoved at the back of his father-in-law's shed turned out to be a spy radio from World War Two.
The man bought in a big "heavy green box" to show expert Mark Smith, which he found when he was clearing out his relative's shed after he passed away.
Thinking it would make a great toolbox, the man kept it safe but was shocked to find out what was inside it when he opened it up.
Explaining how he came across it, he said: "It was in one of my father in law's barns or sheds, we were just sorting through it when he died and I saw it and thought 'That will do, it would be a lovely toolbox.'"
"It says on the front of the box, Sergeant F.L. Church and a service number and then it says royal signals," Mark replied.
"Now the service number, is a World War Two number and actually, what I would say, is like you thought, it’s a toolbox.
"Because what I think it is I think it’s a spares box, probably out of a vehicle. But that’s not what’s inside it is it?"
He then opened the "toolbox" to reveal its intricate insides and exactly what it was designed to do.
"Some of those missions that they undertook were definitely going to be fatal. It’s actually a really quite special piece of equipment," he said, giving his verdict.
"Now, it’s actually quite a complicated piece of equipment, in as much as it can be powered by any source of power that you can think of.
"So you can plug it into the mains if that works, you can plug it into a battery, you can plug it into a car generator, you can plug it into anything that can power."
It would have been used in the war by a Special Operations Executive and is known as a Mk 3 B2 radio.
"This is a real treat, this is a real piece of World War Two history from the very darkest places across Europe that you can never imagine," he told the shocked guest.
However, the guest was in for an even bigger shock when Mark revealed just how much the radio could fetch.
He said: "It’s worth somewhere between £10,000 and £15,000. That’s not a bad toolbox to find in the shed, is it?"
