A Spanish Civil War "Republican" Czech M30 Helmet in good to very good condition. The helmet maintains good original paint with a nice chin strap but is missing the liner. The Czech M30 helmet was a Czechoslovak design introduced around 1930, influenced by earlier Austro-Hungarian and German styles, and known for its simple, rounded steel shell and practical construction. During the Spanish Civil War (1936–1939), large numbers of these helmets were exported or otherwise acquired by the Spanish Republican forces, who relied heavily on foreign-supplied equipment due to limited domestic production.
