This Luftwaffe M1935 helmet was found in Norway in 2003.  The helmet is believed to have been worn during the battles in Normandy between June and September 1944.  The helmet was originally issued in a double decal configuration but later repainted by brush with a thick coat of matt "panzer tan" paint.  The colors of brown and green were then spray painted over the surface of the helmet.  Combinations of both hand and spray painted camouflage helmets are more common than what modern helmet collectors tend to believe.  This process is explainable in the sense that most helmets with camouflage configurations were painted at military supply and distribution stations.  One can image an "assembly process" that includes several soldiers painting helmets with a brush while others are finishing up the process with spray paint after the tan paint has dried.  None of the decals remain visible under the paint.
