1-600 German WWI Iron Cross Style #2

1914 orders were issued to paint a black iron cross on the top and bottom surfaces of the wings and on both sides of the rudder. It was also often used on both sides of the fuselage.  No specific  or formulas where issued and styles varied widely.  White background were not always used. Roundel placement and size varied from midpoint to extreme tips. 
 
By 1916 orders were issued to remove the white background and all crosses were to be surrounded with a white boarder.
