Perhaps the most easily recognized military helmet of the 20th century is the German Stahlhel. In the revised and expanded edition of this classic, Floyd R. Tubbs and Robert w. Clawson identify and classify the Stahlhelm and relate its history, designs, features, and uses. No single nation has produced such a wide variety of helmets as did Germany in the early part of the last century, from civil defense to fire and police forces to airborne forces. Though based on the same concept, each model, design, and variation was constructed with a specific purpose, with the shapes for the helmets differing, the metals occuring in various weights, and the strengths and qualities and the liners being unique to each category. As the only book on the German combat helmet currently in print, this edition, with its detailed drawings and illustrative photographs, will appeal to the collector as well as the military historian.
