Field Police (Feldpolizei) units of the Order Police (Ordnungspolizie-ORPO) were issued helmets that possessed the common insignia of all police helmets.  This consisted of a silver eagle and wreath superimposed on a black shield for the left side of the helmet, and the National Socialist Party decal on the right.  The first of these insignia to be produced were intended to be used exclusively on police helmets.  This type came without a silver border around the eagle shield.  At the same time that this decal was introduced, a similar decal with a silver border was issued for use on all Fire Protection Service (Feuerwehr) helmets.  The premise having been that the silver border would enhance the visibility of the eagle shield against the black paint of the firemen's helmets.  Interestingly, both decals were used interchangeably between police and fire-fighting units.  Field Police helmets utilized both types of insignia which can be found on all helmet models including the M1935, M1940, and M1942 combat helmets.  Field Police units always used both insignia on their helmets regardless of regulations issued by other branches of the Wehrmacht and Waffen-SS.  As a result this has become a trade mark feature of Feldpolizei helmets.  In some rare cases, Field Police helmets can be found bearing only the eagle decal.  The assumption being that two decals were unavailable at the time of application, or that the National Socialist Party decal had been painted over during a field repaint or camouflage effort on the part of the individual soldier or his unit.
