This is an example of a standard issue Royal Air Force service coat issued at the end of the World War I. The use of the standard army pattern continued with updated RAF insignia replacing those of the Royal Flying Corps. The RAF officially adopted the familiar blue gray color on September 15, 1919 but the use of the khaki army pattern continued to be used until 1924.
This coat was worn by Capt. Cyril Nelmes during and after the war. The specifics of Capt. Nelmes' service are not known at this time.
