I explain it away as pictures of mock-ups. I made a few conceptual models myself back in the day. You have to remember this is back before CAD, back when the nation had real draftsmen. This thing was obviously very complex. It was the way we did things back in the day. I’ve personally seen several different style water and wind tunnels. They worked.

They're not mock-ups. Those are all official NASA images, ostensibly from the moon's surface (See AS11-40-5922).

To my knowledge, NASA has never claimed that any LEM Hasselblad-like photos (with reticules) were made using black sky or with a regolith simulant.

Other anomalies, such as below, left-to-right, showing:
  1) a still encased Rover while Rover tracks are already present near the LEM (AS17-140-21370),
  2) a Rover away from the LEM with no tracks in front or behind it (AS17-137-20979), and
  3) two different pictures, said to have been taken on different days at different times of day, 4.5kilometers apart, one including the Rover (top), the other not.
