Officers in Christchurch are appealing for witnesses and anyone with information to come forward after a burglary in the town centre.
The unknown offenders have forced entry to the Mill Gallery and stolen cash as well as antique firearms and three swords.
The incident happened between Sunday 1st and Monday 2nd September 2013.
Police Constable Bill Nightingall, of Christchurch police, said, "The antique firearms taken are not loaded and do not pose any immediate danger to the public. However, some are over 200 years old and should not be operated.
"The shotguns require gunpowder with other materials in order to be fired, and this will only be sold by specialist outlets.
"It is possible members of the public may be offered these items for sale in strange circumstances at unusually low prices. If this happens, we would like to hear from you."
