Just been catching up on this thread, which I should have been a part
of :-)  I'm not going to get into details here, but I would like to

What is the reference for the 140-tonne thick legs?  I've seen this
alluded to a few times on list, but never read anything about it
elsewhere.  Hokannen (1986) concludes that "The limit is suggested to
lie between 105 and 106 kg. A possibility for a still higher mass, in
case of new adaptations, is not excluded."
