Offered is an original World War II U. The cap displays a 4th Infantry Division insignia, which appears to be a post-WWII veteran-era addition. Division shoulder sleeve insignia were not regulation on overseas caps during wartime service, and this example is best interpreted as a legitimate postwar personalization by a WWII veteran, likely for stateside wear, reunions, parades, or keepsake purposes. This is not a modern reproduction and not a reenactor-modified cap. The 4th Infantry Division insignia is believed to be postwar, added by the original owner or veteran.
