And that's a very good historical source being as it is a Fokker factory photo. I didn't have a photo of the aircraft I was modeling so I just went with the style of cross that was in the drawings I had. Obviously there's a good deal of complexity in this "what type of cross and when" issue. But I continue to believe that the sort of cross most commonly seen on eindecker models (as typified by the models on the anglefire link) is just plain fantasy - a sort of myth that has worked it's way so deeply into the modeling community that it may never be dislodged.
