It was never called the L100 by Lockheed who built the thing. It was known as the L382 (which is what my type rating says). The L100 is the dual rail system installed in the aircraft. The story I hear is that when Lockheed was demo-ing the thing to the USAF the captions on the bottom of the story boards depicting the aircraft and the dual rail locks were reversed and some folks have called it the L100 since then. The civilian version of the C130 is called the L382 by its manufacturer and by the FAA. Doesn't really matter what the "Delta Blogger" says. All models of the Hercules flown by Southern Air were the L382.
