Forward of the armored bridge.

First I found this image on West Virginia:

It did seem to be looking either forward or astern, and if you look in the background, you can faintly make out a large caliber gun barrel.

Next, I found this image of Maryland:

Notes say to look above the superfiring forward turret. Sure enough, in front of the armored bridge above that turret is "a box" with black barrels sticking from it.

From this Navsource page:

Comes this image...an overhead view. Look forward of the armored bridge. You can see the mount in the same position as on Maryland:

The above is way down. You'd be better off going all the way to the bottom, work your way back up the the blue subject line about post war and scrapping, then counting 11 images up from that line.
