This black-and-white line drawing depicts a vintage military steel helmet, likely modeled after mid-20th-century designs such as the M1 or Stahlhelm, featuring a prominent rounded crown, extended rear brim for neck protection, and a textured chinstrap with two rivets. A subtle horizontal ridge across the dome suggests ventilation or structural reinforcement. The minimalist style emphasizes form and function over ornamentation, making it suitable for technical diagrams or historical documentation.
