Kongsberg M52: A Line-Throwing Rifle (or Harpoon Gun)
This video explores the Kongsberg M52, a unique line-throwing rifle developed by the Norwegian factory. Introduced in the 1950s and used into the 1970s, it repurposes a Mauser action with a smoothbore barrel. It fires a 12mm blank cartridge to launch rescue lines or, in a variant, to harpoon whales. The example featured is a line-throwing version, complete with its original case and accessories. It highlights Kongsberg's history of producing specialized maritime firearms.
