Large whiskey bottle (Fallout 3)

 is an item in Fallout 3, useful only as Rock-It Launcher ammunition. In Fallout 3, there is a spelling discrepancy: there are "Empty Whisky Bottles", but the filled or large ones spell it "Whiskey".

There doesn't seеm to be any large whiskey bottles with any whiskey in them
 * Large whiskey bottles have no real practical use other than Rock-It Launcher ammo
 * Somehow the Lone Wanderer is able to tell Scotch and the Large Whiskey Bottles apart
