Hood code zero or asym?

Not sure exactly what this sail is (comments appreciated). Unsure of age too, as it came with the boat, but appears very lightly used. I put it up to take a look. Snuffer goes up and down well. I had it tacked down close to the horns and sheeted to the transom. Worked fine reaching. Does not seem to require a sprit. Perfect for short-handed cruising. Sail measures approximately: luff=33', leech=27'8", foot=22'7" Asking $1,200
