Now those three are beautiful beasts. I know that these ones were real, not AU, but do you think that you could try making the 747-100 and -200 in the TWA livery? Just a thought.
If you want to make N93119 it's rather simple...
(1)- Find the base pic for the FD Scale 747-100,
then,
(2)- Paint it in the TWA 747-400 livery seen here
