Moon camera?

I don't really have a post for the weekend, since I've spent it at home with mis padres, but I did remember something:

The STADAN book says how the camera was mounted on the moon lander!!

"During the first nine minutes of the broadcast, NASA alternated between TV from Goldstone and Honeysuckle, searching for the best one. Neither was very good as they both came from 26-meter antennas (as opposed to the 64-meter dish at Parkes). Because of this, they could only accommodate blurry images using what was called ‘slow-scan television’—a picture transmission method used mainly by amateur radio operators to transmit and receive black and white pictures. There was one more thing. Not only was the TV picture grainy and blurry, it was upside-down! 
This was because as Armstrong began his 2.4-meter (8-foot) descent down the ladder, he pulled a D-ring which dropped open the Modular Equipment Stowage Assembly (MESA) containing the television camera. Due to the way the camera had to be mounted, however, when the MESA dropped opened, it was upside-down....
In a little known vignette of history, the way the camera was mounted in the MESA and the way the compartment dropped opened caused the camera to be slightly tilted with respect to the true horizontal-axis of the LM. What this meant was that an even more harrowing appearance was added to Armstrong’s already dramatic climb down the ladder. In reality, although the incline of the ladder was indeed quite precipitous at 65ยบ, it was not as steep as seen on TV, which gave the illusion like it was almost vertical."
Tsiao, 176-178.

In other words: There was a conveniently located outdoor sort of pocket in the lunar lander, mounted a little off true, that made for some hella dramatic camera angles.  Somebody with access to a 1:1 replica or, even better, an actual lunar module could probably wander around until they got a good look at the ladder to find that D-ring, because it's probably pretty big for Armstrong to have been able to pull it. Those gloves were fairly dextrous, but they were still pretty thick and I doubt he would have been physically capable of grabbing anything too terribly delicate as he was climbing out of an already slightly awkward space craft.
