Sculpin's third war patrol, out of Fremantle, was plagued by torpedo problems, and ended with no results. On her fourth patrol she claimed hits on a 4,000-ton freighter, two 8,000-ton tankers, and a 7,000-ton freighter. She was credited with the latter, but JANAC was unable to confirm the sinking from Japanese records after the war.
Many years later the captain of the Sculpin, Lucius H. Chappell, had a minor role in the movie Operation Petticoat.
Here is another site related to the U.S.S. Sculpin. This one has some great photos, including the one shown in today’s N.Y. Times from the post above. Sculpin was involved in the salvage operation for Squalus back in 1939.

D’OH! That is the same site you linked to. Good photos, nevertheless.
