I want to say the Tornado deluxe with the double bars and the tank was only offered in 1959 and 1960. I don't see an option for a deluxe in '61 and in '62 it was replaced by the Typhoon.
I do believe it is different from the earlier straightbar tanks since they were only on heavyweights until this point. I still won't say with any certainty but that's what scrolling through the catalogs suggests! Good luck.
