Some of you are so well-read in these matters, you might have seen this before... but this adds a little wrinkle to the “boxes in the window” discussion... Very interesting... This Congressional Committee made the determination that the boxes were moved in the interval between the Dillard and Powell photographs (see para #270 below)... Interesting...
The following is from:
Investigation of the Assassination of President John F. Kennedy / Volume 6
By United States. Congress. House. Select Committee on Assassinations (1979)
The source for the following is linked below the quote (JFK.hood.edu....) I’m not certain if this is from the Committee report, but it does seem to summarize and conclude on the same note...:

A look at the U.S. Naval Observatory's data for Dallas, TX at 12:30pm on 11/22/63 shows the exact position of the sun:
#declare alt[ 383]= 37.0 ; #declare azimuth[ 383]= 184.9;#declare time[ 383]= "12:30"
Simple trigonometry shows that with the clear weather and the height and orientation of the windows, that the boxes in question, in the article you posted, would be lit by the sunshine. I don't know why the study didn't take all of the factors into consideration. It appears that they make some assumptions that are entirely incorrect.
Here's an image using my 3D virtual model with the sun located properly for 12:30pm on 11/22/63. This is from just west of the sniper's nest looking east into the nest. This should give you a rough idea of the situation. And yes, I have verified the sun position is correct.
