Last year I built this model of the USS Marblehead, and although it is well-made and quite detailed, it seems to be a 1941 version (with alternate tall mast poles for earlier times) but it comes with all 8 casemate positions -- to make it a truly updated (1941) model, as I did, you must abrade away the hull bulges for the two lower rear casemate positions and cover them with something like Evergreen sheeting to make a seamless transition from the old casemate positions to the surrounding hull.
