Yes - made in 1898 to 1900 according to the serial #. Apparently Sweden passed a law that a moose gun had to have rifling. Thus Husqvarna started making SxS's with one barrel rifled and the other smooth. The round ball loads were apparently loaded in brass cases with black powder and the shot loads for the other barrel, were loaded in paper with the new smokeless. As well, there was apparently no rhyme nor reason why some had twisted rifling, while others were straight, except the straight rifling shot decently with standard shot loads. This was a nitro proofed gun.
