This one just came in , it's a "Helferinnen Haube" for a German Red Cross ( DRK ) nurse.
Not as "shocking" as a visor cap but I Always wanted to add one of these to my DRK headgear.
Also used postwar , so you have to know where to look for when you want an Original wartime example.
The red cross is BeVo woven and machine-sewn to the cap.
There are two small metal buttons ( to hold the integrated elastic strap ) covered with cloth ( postwar buttons were plastic ).
Nice feature are the initials of the nurse , "R.B".
