Mystery Moth

Help appreciated with this rather battered moth. I've taken lots of pics of it but can't get any more markings to show. It has quite a dark grey hind wing.
Trapping has been good recently, the Elephants have arrived, and also a new species for me, a Ghost Moth, and last week a Privet Hawk-moth honoured me by appearing in the trap. A very excited Moth-er woke up her husband at 4.30am ,yelling, 'Guess whats in the trap!!!'
