Except for the taxi weight, that list of features could easily be used
to describe a 747-200B.  The -200B started off with a MGTOW of 785,000
lbs, so taxi weight was probably about 788,000 lbs.

With the 777-200(IGW), the only difference between various MGTOW
optiosn is paperwork and dollars.  Is a 747-100B simply a 747-200B
which doesn't have a MGTOW in excess of 750,000 lbs on its certificate?
