The picture, taken in the 1980s, shows a Labrador among a school group at a memorial to the Dambusters, close to where Gibson's dog was buried.
Nigger was allegedly killed outside the main gate of RAF Scampton and is buried outside the hangar at Scampton (2 or 3??). The 617 Sqn memorial is at Woodhall Spa a mere 15 miles away.
Bloody nimble these dead dogs.
