ALT We’re really sad to share that Kelham Island Museum suffered a break-in at the weekend which saw the theft of 12 items relating to the city’s metalworking history. The objects, which include items from Sheffield Assay Office, the Ken Hawley Collection Trust and lenders to their collection, are an irreplaceable testament to the skill and excellence that has earned Sheffield makers a global reputation. Their historical significance is far greater than any financial value they hold. Some of these items are likely to find their way onto the market and are very distinctive – we’d be hugely grateful if you, our Twitter friends, could keep a look out and contact South Yorkshire Police if you have any information that might help their investigation. You can find contact details and images of the objects in the link above.
