I also have my "two cents" to put in. I agree that the swastika needs to be depicted as an authentic historical marking for most WWII era German ships. Although I understand contemporary sensitivities about its meaning, we cannot ignore that Hitlers NAZI Party was but one example of the worst of human behavior. Nobody questions the placing of the Red Star or the sickle and hammer emblems on Soviet tanks, ships, and aircraft, yet Stalin was responsible for far more inhumane deaths than Hitler ever was. Similarly, Communist Chinese markings can equally represent the hundreds of millions of innocents murdered by that Party. Equally, the Rising Sun emblem on Japanese vehicles represents the brutality with which that nation's military treated the peoples which they conquered in WWII.
In other words, the sensitivity over the displaying the swastika emblem on German aircraft or ships seems misplaced to me. If we are modeling for historic accuracy, it needs to be placed on those vehicled on which it was carried.
