Griffon did cross my mind. In which case, with the exhausts like that, they'd go into the main collector, and it could be a Shackleton AEW 2 ?
Karl, I don't remember standing in front of the Hind and having my pic taken! (Cross my palm with silver, and i might post the pic you mean!)
It was the shadow of the wheel whizzing past the cabin which was the giveaway!!!
I'll be back in a short while with something - if I can find something which aint p*ss easy !!
