A Cambridgeshire councillor and former town mayor has been found guilty of possessing a firearm.
Police arrested Jonathan Farmer, 57, at his home in South Brink, Wisbech, on 10 January.
Before the trial, Farmer, who has been suspended from the Conservatives at Fenland District Council, told the BBC his German Walther PPK pistol was a gift from a friend.
He is due before Cambridge Crown Court for sentencing on 29 August.
Farmer, who was Wisbech's mayor from 2008 to 2009, also said before the trial that he was told the World War Two pistol had been deactivated.
He added it had "sat in a cupboard for about 25 or 30 years".
