The Czech M30 helmet or VZ30 helmet , was a design that found wartime use with the Republican forces in the Spanish Civil War. Its unusual design featured two ventilation lugs that protruded from the helmet and was uniquely found worn by Spanish soldiers, both forwards and backwards due to a minor difference in the length of the brim not always easily discerned by the common soldier. The helmet also served briefly with the Dutch and other small export customers. Comes with leather liner and chinstrap. Emblem loop on the front of the helmet can be used to attach Spanish Eagle emblems as sometimes issued in Spain. Steel helmet. New.
