This is believed to be the device that led to the evacuation of the former Swan Hunter site on the River Tyne.
The former shipyard in Wallsend was cleared after police were alerted at 11.30am to the discovery of what is thought to be unexploded munition from the Second World War.
A HGV driver, who transports dredged materials away from the river, said he had arrived at 6am and his was one of around 10 wagons stopped from entering the site.
"We've been stopped from going down there because they said they may have found an unexploded bomb in the river," he said.
"I've been waiting in the queue for ages. The lads on the weigh bridge said there's been a three foot shell found.T I haven't seen anything myself, because they are preventing us from going down there from the top car park."
A Northumbria Police spokeswoman said: "At 11.32am this morning, Tuesday, December 1, police received a report of a possible WW2 munition found at Swan Hunter, Wallsend.
"Staff at the site have been evacuated temporarily as a matter of precaution.
"Officers are currently on the scene and this is all the information we have at this time. "
