United States Navy film #MN-4273 Here's Your Letter, Sailor!
Illustrates the operation of V-Mail in the U.S. Navy. Shows how mail is delivered to ships, and explains the proper format to use to address letters so they don't go in the Nixie pile.
I can't find much about this film but I think Paramount produced this. I don't recognize the character actor sailor but he is pretty fabu.
National Archives description: "On the delivery of mail to sailors at sea. Reel 1, mailbags are transferred by launch from a PBY seaplane to an aircraft carrier. Describes typical letters. Mail is sorted at the San Francisco Fleet Post Office.
Reel 2 explains how letters should be addressed. Mail is loaded on a Mars seaplane, flown to New Guinea, and reloaded onto native canoes and oxcarts. V-mail is processed by microphotography.
Reel 3, five mail bags are flown all over the Pacific area before arriving at their destination aboard a battleship. Stresses the improvement in morale created by prompt mail delivery."
