Its exact origin is unknown but the foot parts suggest a Finnish origin. The suit, which was used in short underwater work like checking the conditions of the bottom of a ship, was donated to Raahe Museum by Captain Johan Leufstadius (1829-1906), who was a master mariner, merchant and ship owner.[citation needed] The conservator of Raahe Museum, Jouko Turunen, tailored a perfect copy of the old suit in 1988. The copy has been successfully tested underwater several times.[citation needed]
