National tricolored decals were manufactured by a number of firms.  The basic design was consistent with patent records that indicated the decal was to be manufactured in a standard 40mm x 33mm size.  Some decals were applied using lacquer while others were printed on water slide paper with a glued backing material.  No differences existed between the type of National decal used on German Army (Heer), Navy (Kriegsmarine), or Air Force (Luftwaffe) helmets.  Essentially all service arms of the German Armed Forces (Wehrmacht) utilized the same decals.  Samples of the various types are illustrated below.
