The Merlin powered Wellies are as they sit the places where the burned if you look carefully (bad colour I must admit,) you will see the sand bags of a blast shelter, and the dead place is where the beyond use airframes were pushed or lifted to, I do have another picture of a welling front view after it had landed with U/c up and it is cler to see the Merlin PP, I too am surprised for I thought the Merlin Wimpeys were only for High Altitude use, and on double checking the faded writing of my old Dad on the reverse of the piccs it clearly says WD N Africa, I would say that is Western Desert, and dated 1941, looking at the Diarys that I also have, that puts Dad in Libiya, and by Feb 1942 he was at a drome( as he puts it)near a place called Aboukir,
I will post the other pictures when the net has gone quiet its much faster that way.
