Factual error: When in his office after being sunk, Clark Gable and Don Rickles are together. The phone is in the background on the corner table. The phone in the office is a 1950s model rotary phone with push buttons for several lines. This was not available in 1942-1943. There is a wall phone hanging on the window frame that is also a 50's model with a 50's handle.
Question: At the beginning what was wrong with the young sailor drawing number 7 in the money draw?
