I am not speaking of the guns themselves but turret shape. Don’t know the MK number of turret but they do look similar between Porter and Helena. The reason I ask I have the Midship Helena kit and the CW kit of same. The turret shapes vary in each kit and I am not satisfied with appearance and shape of them. I am debating buying the turrets from Model Monkey of the Porter/Somers Class DD if they were same turret type. Any help will be greatly appreciated.
