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.
