A very unusual period time German double decal Firebrigade helmet. Not a common M34 pattern. It looks to be a sort of self-made example by a small company. There is a WERKZEUGE WEINBERGER tag to the sell. This company specialized in producing tools and might also done helmets in a certain number.
Original black color. Original decals (again, slightly unusual shape). Original liner (Ersatzmaterial) and unusual US made chin strap (one strap damaged). TUCK-TITE marked clipper (period time?).
