Now that I look at those historical pictures, they may have done the vertical additions in front of all the windows to "fix" the mismatches created by adding on. The windows weren't the same, the spacing wasn't the same, and the brick was obviously not a match. So the vertical top-to-bottom architectural features, while ugly, disguised the patchwork look and made it look like an intentional 4-story building. Probably for cheap, too.

Looking at the significant shades on only 1 side of even the original building, perhaps they were also necessary to reduce heat on the equipment inside.
