Well...

I have found drawings. However, counting up the guns on those drawings does not exactly match the Wiki listings. Which entry is in error...Wiki, or these artists...I could not say. You will get "the general idea" at least, of how her armament evolved.

See the line drawings on this page comparing 1938, 1942, and 1944:

Now, see the undated line drawing a short way down from the top of this page:

I have no idea what the notes alongside the drawing in this last link are about, and there's no caption explaining. Changing the quad 40 mm to twins looks like back dating, but changing the single 20 mm to twins is forward dating. If you compare this image with the one labeled as 1944 in the top link, you will see this image is definitely a later fit...it has been upgunned. More quad 40 mm mounts added, and the original twin 40s changed to quads. Further regarding the 40 mm's...note the bow twin mount in the '44 drawing is gone in the later drawing (the change of the forward twins to quads was deemed sufficient forward protection.) Note also two twin 40 mm guns just aft of the after 5 inch guns, and they stay twin from '44 to '45. I count 56 40 mm guns in the undated (but obviously later) drawing while Wiki claims 54 40 mm. So, all the "deleted" and "40mm twin " notations along the sides doesn't make sense. Only one quad mount needs to be changed to get 54 guns. That drawing is deleting way too many. No idea what those notes are about.
