That's right, Greger.
But it is the case here, if you look through all the pics you'll see, it is so that on some pics it is so but not on others. Some times left hangs - sometimes right. This time the sloperis high on the left side , see front view - how high it climbs above the neck line. You think the center back would swing to the left - but in back view (see left side is hanging) we see it swings to the right.
This is the real difficulty in this case.
