According to the Norwood Park Chamber of Commerce & Industry website, Mr. Gurga served as a photographer for Allied bombing missions over German industrial targets. The Chamber site says he was stationed in Great Britain from 1942 to 1945. It specifically mentions Mr. Gurga's service in the 493d Bombardment Group.
