Way back in the late 1960’s I collected most of the Aircraft profiles of First World War aircraft. I used the illustration page to make scratch built balsa wood models. Now I’m using the same reference to paint a Roden 1/32 Fokker Dr1 my second ever plastic kit. The Profile illustration is of Fokker DR1 152/17
However other reference I’ve found online is sometimes different. The Iron Crosses on the wings sometimes have white square backgrounds on both top and bottom wings or neither or (as the Profile) different on top and bottom. Can anyone give any guidance? I note that a famous photo of 152/17 does seem to show square backgrounds to the top wing crosses but I'm not clear if that is a lighter red or a dirty white.
