Here you can download artwork (in PDF format) for decals for the aircraft depicted in the book AS.365 Dauphin II in Emergency Medical Service (SMA vol.3). The artwork comes in the form of layered PDF 1.7 files: one layer contains all the colors except white, and the other layer contains those details which should be printed in white. Note that white is here represented by a dark brown color (the CMYK color 40/70/100/50); this color does not appear anywhere on the color layer. In cases where a colored decal is on top of dark color (on the aircraft), a white decal is also provided that can go underneath.
Artwork on these sheets is in 1/72nd scale, but since these are PDF files, they can easily be resized to other scales.
