Police are investigating after a set of medals were stolen from a house in Sidmouth.
Roger Bristow says the medals awarded to his grandfather Clement "cannot be replaced" after they were taken during a burglary.
Clement Bristow was awarded the Queen's South Africa Medal, the King's South Africa Medal, and the Distinguished Conduct Medal as well as the MBE and King's Police Medal for Gallantry.
His grandson says the medals are part of his legacy.
They were unique, they represented his life, there's a story in the medals.
Aside from their huge sentimental value, the medals are worth a lot of money.
The family has been told the Distinguished Conduct medal alone could sell for £6,000.
Roger intended to pass the medals on to his son who is also in the Army.
He says he hasn't given up hope of tracking them down.
There are lots of feelers out there at the moment in the medal world and various people we've spoken to say it's such a distinguished collection that if it ever does come onto the market it will be noted.
