gitzo ball head dismantling - anybody?
Looking at the exploding drawing, it looks like you need to remove the ring above item d1377.101 to get the ball out.
To remove the rest of the panoramic system There seems to be a horseshoe lock that needs to be removed(bottom part of D1377.109)
At least that is how they use to mean the ones i'm use to look at.
Hope it helps.
