That sounds pretty plausible, but I’m not sure.

The windows are only very slightly off center, inconsistent, and even the ones above the clock are as well (although the clock mechanism could extend both up and down).

But I also don’t have any better explanation.

Edited my comment to fix, thanks!

This is less of a source and more like a compilation of resources, but for anything spacecraft related I can always recommend Atomic Rockets. For this specifically, the page on Heat Radiators.
