Fair use rationale in 76 mm divisional gun M1939 (USV): 1. Old, apparently WWII-era photograph. 2. Copyright holder — if any — is unknown. 3. Relatively small and low-res, unlikely to have any effect on a potential market — if there is any — for the original photograph. 4. Used for illustrative purposes only in a specific article. 5. Public domain photos of the subject are hard - if not impossible - to find.
