Armor - Armor - Designing armor for American Soldiers. In the Armorer's Workshop of the Metropolitan Museum of Art, N.Y. where under the direction of Major Bashford Dean, Ord. Dept., U.S.A., and Curator of Armor at the Museum, armor for the American soldiers fighting in France is being designed. The suits or armor used in medieval times which many collectors have brought to the museum were carefully inspected and the good points brought to the museum were carefully inspected and the good points brought to bear in fashioning this modern armor. The actual labor is being performed by Assistant Curator of Armor at the Museum, Daniel Tachaux and his assistnat Sergt. Jacques Bartel, of the Ord. Dept.
