Owned a SuperSport, great, full sized, luxury rifle. Mine had been abused terribly prior to my purchase, and I didn't realize their rarity till I'd traded it away. Magazines are rare and expensive as are the proprietary cantilever scope mount.
Mine had lux wood, skip line checkering, and high gloss bluing. Pressing a button at the receivers rear allowed bolt removal, a unique design.
Wish I had taken pictures of mine.
