You'll have to do a little digging through this list to find out the specifics regarding the origins of ATA's 1011 fleet, but you should find it well worth your while:
The entire website is a wealth of 1011 information.
The L-1011 was a great airplane, loaded with advanced (for the day) technology), and flight crews loved it.
And, seeing that my dad was a contracts administrator for Lockheed for 30-odd years, on the 1011 project with Delta, ANA, Saudia, Court Line and others, it kept food on our table for many years.
