I recently had a chance to visit the US Space and Rocket Center. While I was there, I saw a lunar module. It is very clear that the ascent portion is a mock-up, but the decent portion looks real, although it seems to be smaller than the one in the Smithsonian (Could just be because it is in a corner, the Smithsonian one you can walk around pretty good). I've seen mention on the internet that the descent stage was a test article, although I have carefully searched the lists and not seen any mention of this. Any idea as to what the origin of this test vehicle was? Thanks!
What is the origin of the Lunar Module in the US Space and Rocket Center in Huntsville, AL?

It's an engineering test mockup.
This model incorporates an engineering model of the Descent Stage (used at MSFC, designers of the Lunar Rover, for studies and fit checks) with a fabricated Ascent stage (note the lack of detail in the hatchway area compared to some other LM images)
1$\begingroup$ Thanks! Been driving me crazy trying to get the scoop on it. $\endgroup$ Jun 19, 2021 at 0:56
2$\begingroup$ The Saturn V there with the V-2 lying at its base is mind-blowing. Also love the Shuttle Centaur and the MPTA. Great museum. $\endgroup$ Jun 19, 2021 at 1:00
1$\begingroup$ Was walking underneath it all morning long. It's pretty insane, to say the least! $\endgroup$ Jun 19, 2021 at 2:10
1$\begingroup$ Also, Shuttle Centaur sadly is no longer there... It seems it has ended up in Ohio. $\endgroup$ Jun 19, 2021 at 2:21
$\begingroup$ Wow, glad I got to see & photograph it. But it seems fair, Lewis did do all the hydrogen stuff. $\endgroup$ Jun 19, 2021 at 2:23
