German Balkankreuz in the early war style. This design is useful mainly for the upper wings of most German aircraft through to 1943, when the later, more simplified styles began to supercede it. (It differs from 600-GE-1 in having a much thinner and therefore less visible white band; on the very smallest designs this is very marginal indeed; I'd recommend sticking to 600-GE-1 for the 24" and 30" designs.)
These decals are scaled to represent 24", 30", 36" and 48" crosses in 1/600 scale, so they're pretty small decals.... Actual sizes are 1mm, 1.25mm, 1.5mm and 2mm. Note that while intended for 1/600 aircraft, they may also come in handy for other models, eg. tank markings in larger scales.
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.
