This is a highly detailed, all 3D printed kit of the US World War 2 submarine Nautilus.The kit can be built as either full hull or waterline and represents the sub as she was in 1943 when extra torpedo tubes and 20mm guns were fitted. The kit includes custom rails and some extra parts to allow for loss or breakage!
