Some of the very early Relum's were fitted with 3 springs, must have looked like a load of curly spaghetti.
Mind you the sales and marketing people who named the rifle Tornado score a good 10 out of 10 for sheer optimism.
It's true that it's not a new idea, as a 1908 BSA I have sports a nice pair (ooh er missus).
