Police are investigating the theft of rare and valuable antique musical instruments from Co Down earlier this week.
The 30 accordions, worth a considerable amount of money and dating back to the 1950s, were stolen in Comber.
The PSNI said the instruments could now be anywhere and they have appealed to the public for help in finding them.
In particular, they are seeking information on a white six-berth Fiat Ducato motor home, registration number W91 PVM.
It is understood the owner of the instruments was visited by two men who said they wanted to buy an accordion for a relative.
They asked to meet him in west Belfast the following week to discuss the deal further. The man waited but no one showed up.
When he returned to his home, he discovered that his motor home and all of his accordions had gone.
Assorted items of jewellery, with great sentimental value, were also taken.
Detectives believe the motor home could have left Northern Ireland.
A spokesperson for Newtownards PSNI said that the items are rare and specialist.
The spokesperson said: "They are not the sort of thing you would normally see in a pawn shop or being offered for sale door-to-door or even on websites.
"You would not pay a couple of hundred pounds for an instrument like this and anyone who wanted one knows what they are looking for and knows a reputable seller."
Images have been released of instruments similar to those stolen in Monday's burglary.
