Hello all,
Richard Hess has provided us with yet another thought-proviking picture:

----- observing your example closely, I cannot help noting that the impression or "shadow" is very distinct on the large centre area (and on the extreme left, which would have been completing this impression when the box was closed). However, the "other" side of the reel has only given a less sharply defined outline, even on the top and bottom that would have had the same relationship to the reel. I would think that this indicates that the box has been stored horizontally for most of the time, the reel resting on the carton, whereas there was some space between the reel and the opposing side of the box, giving a less sharp shadow.
----- but is it really acid attack on the carton and not e.g. a lubricant? And how is the reel itself - it looks slightly frosted - does it have a deposit that sticks to your fingers?
Just asking before you send the material back.
