The German Stahlhelm is perhaps the most recognizable image of World War II. Manufactured in its millions, it was used or copied by many countries. It is still one of the most collected relics of the war; but despite its relative availability, prices have reached levels that challenge collectors to protect themselves by acquiring in-depth knowledge. This book, by a collector of 30 years' standing, offers a detailed masterclass in the patterns, component parts and finishes of the combat helmets used by the German Army, Navy and Air Force. It is illustrated with a superb selection of rare period photos, colour photos of collected examples, and striking colour paintings.
