The wreckage of the aircraft is spread over a fairly large area with two reasonable collections of pieces.

The collection furthest up the moor has these pieces of undercarriage, a single cylinder, bomb rack and smashed remains of the crew access door.

Above it a photo showing the bomb rack with skinning panels, the single cylinder from the aircraft's Mercury engines can just be seen on the right of the image.
