German Balkankreuz in the mid-war style. These are black with white edging; the extra black trim was dropped by this stage. This design is most useful for 1943 or thereabouts. Earlier aircraft will more likely need 300-GE-1 and / or 2, and later ones 4 or 5.
These decals are scaled to represent 30", 36" and 48" sizes in 1/300 scale. The actual sizes are 2.5mm, 3mm and 4mm. While they're intended for 1/300 aircraft, they will of course come in handy for vehicle markings in larger scales as well.
These designs are of course supplied on the same paper as all of the others (actually a very pale blue) - I've just given them a coloured background so that the white is more readily visible.
