Originally delivered as a Goodyear ZNP-K, but converted to ZP2K in the early 1950s. K-72 (Bu30194) saw action during WW2, and on April 18, 1945, dropped an acoustic torpedo against a German U-Boat. Although a destroyer heard an explosion no debris surfaced so it was not credited with a kill. Seen here at the 1953 Dayton Air Show, with "Join the US Naval Reserve - Be a Naval Aviation Cadet" titles.
