A £25,000 reward's been put up for information that helps find a 600 year old jug stolen from Luton's Stockwood Discovery Centre museum.
Insurer Zurich has put up the cash for the safe return of the Wenlok Jug (right), which was taken from a high-security display cabinet during a break-in on Saturday 12 May 2012.
The bronze jug - worth hundreds of thousands of pounds - is decorated with coats-of-arms and badges and inscribed with the words "My Lord Wenlok". It's said by experts to be of national significance.
Zurich, which insures the museum, is offering the reward for the return of the item in a reasonable condition to anyone who had no involvement in the offence.
Paul Redington, from the firm's major loss claims team, said: "Zurich fully realises the importance of the Wenlok Jug both to the museum and to the people of Luton. Stockwood Discovery Centre is a place where people can freely view and enjoy such objects.
"These cases are not just about writing a cheque. Ultimately, Zurich wants to assist the museum's efforts to get this jug back where it belongs and so that it can be enjoyed by future generations.''
Anyone with information about the theft is asked to call Bedfordshire Police, in confidence, on the non-emergency number 101 or by text to 07786 200 011.
Alternatively, information can be passed anonymously to Crimestoppers by calling 0800 555 111.
