Japanese "War Tubas" (Acoustic Locators); 1930's
Before radar was invented/widely used (WWII), this is how the Japanese located aircraft in their skies. They are not in fact tubas, but do bear a striking resemblance. It would be fun to stick a mouthpiece into it and blow for all you're worth, wouldn't it?
