There was a memorial site outside 617's hangar at Scampton to 'Nig ger', referred to as 'Nig ger's grave'. But whether the real black Labrador was buried beneath is unlikely.....
It was a JP's secondary duty to look after Nig ger's Grave - weren't you the lucky one, Specaircrew? Whilst we of the rather more senior and infinitely superior 35 Sqn used to pee on Nig ger's Grave when you weren't looking!
