The Crusader was a highly innovative design that wasn't enough to save Hi Standard. Sadly Hi standard went under, many years ago. I'd love to find a crusader but there weren't many made and they're quite expensive if you can find one. The design of the action was VERY advanced and I'm surprised someone hasn't attempted to bring it back.
