I have a old double barrel shotgun I am trying to find out about. The name Nik Szalier Comp Wien is on the top. The numbers 22626 164 125 and 16857 L33 107 are under the barrels. This is a side by side shotgun/rifle combo. Any help on finding out more information on this gun would be appreciated. I also need to know if parts are available anywhere as the stock is broke. Thank you
