This photograph documents a stripped motor chassis paired with a wheeled gun carriage bearing an elevated cannon barrel — most likely a captured German anti-aircraft or field gun. Though filed within a WWII-era collection, the construction and wooden-wheeled carriage point instead to World War I. After the 1918 Armistice, the U.S. War Department shipped thousands of captured German guns to American cities, including Cincinnati, Ohio, for public exhibition during Victory Loan campaigns. Numbered '54' for inventory purposes, this image likely records one such trophy piece prior to public display. Project: 218708
