It's a Z BuZZz...i had a buzz from a few years ago that had a more 'classic' stamp that said 'super straight modified wasp'. I'm guessing its a little older...really though...if i wanna be REAL? like REAL REAL, ITS A BUZZZ who cares?! get any other Z buzzz of the similar weight and be fine with it, learn to throw more consistently. A Buzz is a Buzzz (if from same plastic and near weight) I have 2 BUzzz'z now, one flat, beaten in a bit 168g and one more domey and 174g....really, they fly pretty much the same, **** dude, dont worry about it.
