Don Winslow of the Navy (Serial) - Region 0

The serial was based on the comic strip by Commander Frank V. Martinek, which was approved by the US Navy. The strip gained new meaning with the approach of World War II, which would also affect the serial: "Its presentation as a Universal serial in October 1941 - just before the infamous attack on Pearl Harbor in December - was one of the most timely contributions of the serial field."
