WWII submarine-hunting binoculars

You don't have to be a history buff to think these Japanese military-grade vintage naval binoculars are easily one of the coolest mementos to come out of wartime since the world ruined "Keep Calm Carry On." 

These powerful 150-millimeter Nikon lenses offer a 20x magnification power that are so powerful that one could see a shell land fifteen miles from the ocean. They were built with the intent of gaining a competitive advantage at sea; watching hot girls from the next town over was just a bonus.

Nicholas Brawer (of the crystal cock) exhibits these mirror-polished brass marvels of military technology at his New York gallery for all to gawk at. They're the perfect accoutrement for your military-themed personal yacht — the aptly-named Sea You In Hell.
