Thank you klingongoat
... it was indeed Richard Datin's website I was thinking of, and it was this picture in particular
that I was interested in viewing.
Unfortunately, my memory played a trick on me--I remembered that image being larger; the resolution on that photo is too small to make out the writing on those labels.
Oh well, at least that angle helped confirm the shapes and positions of the windows on the hangar bay observation deck. Thanks!
