Most of the decals were from a "professional" decal sheet, made by Dutch Decal. Only the W and the 7 were home-printed.
Although I tried hundreds of fonts, unfortunately I still could not find a font that really equals both the letters and the digits that are used on planes and helicopters. So I used two different fonts here: Lucida Console for the W and Sitdown for the 7.
