Thanks Cees,
If this came from a wreck then there is only one B17 that I know of in the Edinburgh area that it could have came from.
I have my doubts that it came from the local area at all other than that B17.
My only other thoughts are that one of the ATC members maybe brought it back from a trip to the Cheviot hills. As most will know there is substantial wreckage all over the place there. Not impossible to find a nice piece of wreck for a display item there now is it.
Any other thoughts guys but a bit of a long shot.
