The Antiques Roadshow returns to Plas Newydd on the Isle of Anglesey in Wales, where treasures include a Chinese silver punchbowl, a collection of historical items relating to deafness and a fabulous musical hummingbird. A mystery cabinet with a small brass tap is revealed to have a special purpose for the avid angler, while a magazine rack bought for a few pounds turns out to be the work of great Italian designer Piero Fornasetti. Marc Allum is fascinated by a collection of items relating to deafness, including ear trumpets and vintage hearing aids, and learns about George Downing, a 17th-century statesman who became fluent in sign language after growing up in a deaf community in Kent. A huge Chinese silver punchbowl puts a smile on the face of specialist Duncan Campbell, while the owner of a dynamic marine painting by Montague Dawson is relieved that they went back home to get it after pictures specialist Dendy Easton glimpsed a photo on their phone. The connection between a photo of a young man in an RAF uniform and a photo of the Apollo 11 astronauts moves books specialist Justin Croft as he hears the story of a teenage obsession and a life cut tragically short. Jewellery specialist Geoffrey Munn is dazzled by the jewelled hummingbird that pops out of a gold box, and reveals a value that leave its owner on the verge of tears.
