I have been building the USS Phoenix from the USS Helena model and trying to modify it to fit the USS Phoenix. Previous thread on http://www.papermodelers.com/forum/ships-watercraft/4156-uss-helena-phoenix.html Have finished the 5" open gun mounts, 3 on each side amidships and one on each side on O2 level. The Phoenix did not have enclosed duel 5" mounts. Not having them means that it did not have hoists to bring up the shells, they had to be hand carried to the mounts exposing the handlers to danger as they were not protected. I had to change the blast shield to regular railings if you look back at previous pictures. I find that sometimes I have to change things (poor planning and rushing). I will attribute any differences to updates during different dry-docks. I will not glue them in place yet as they overhang the hull and I would probably damage them as I turn the ship during building.
