The raid has been reported in local newspapers in the hope that someone will recognise the objects and tell museum staff.
There are also photographs of all of the stolen objects on the Portable Antiquities Scheme (PAS) website. Just in case you come across any of the treasures, Will's contact details are on that page too.
(The PAS is the organisation which keeps track of archaeological finds in England and Wales.)
