I'm not sure either, but at least it shows a newer release which apparently would have had some of the same flaws that have been mentioned.  The old/original release isn't suppose to have these "unbuildable" flaws, so your experience with this helps.

There has been a model of this plane, according to Scalemates, since 1945.
