Here is an excellent group of photos of ML #1 prior to it's demolition. The LUT was taken down and stored in the nearby Industrial Area while the platform was converted for Shuttle use and renumbered MLP #3. Note that some of the ECS piping had been removed when these photos were taken. This actually allows a better view inside each level.
These photos were taken by Greg Katnik and sent to me by David Miyatake.
