These photos are provided by Cecil J. Jump of South Bend, thanks to his daughter Jill Hallenbeck. I gather they were taken in the Fall of 1945 in Key West where the Irex was stationed and during trips to Havana and Guantanamo Bay in Cuba. Labeling on the back of the photos suggest that Cecil figures in them prominently.
Interesting views of the deck gun and the 40 mm. gun mounted below the bridge.
