Plot: A valuable vase covered in paint and bought for £1 at a car boot sale, a Martinware bird which cost two shillings at a fete and a rare hair ring bought in at auction, because 'nobody else was interested and I bid £1 and got it' - three great bargains turn up when Michael Aspel and the experts visit Wisbech in Cambridgeshire. There's also an impressive collection of royal invitations, letters, sketches and items from eminent Victorians put together by the librarian at Windsor Castle in the 1860s
