This field covers uniforms, headdress and badges from the 18th century through to Third Reich items from the 20th century. Much of this material can be seen in context in contemporary prints/drawings and other art work, eg bronzes and photographs. I keep a very sharp eye out for, and a photographic record of, all the particularly convincing Third Reich fakes that come my way. Good reference books include: The Emperor's Coat by Rest, Ortner & Ilming (Verlag Militaria) on Austro-Hungarian militaria, Great War period; Shoulder-belt plates and buttons by Parkyn on British militaria; two volumes by King on British military headdress badges. The National Army Museum (Royal Hospital Road, London SW3) has an excellent bookshop and display covering the British side of this great subject.
