I am in the process of purchasing a second hand Predator BK Rush break cue. I'm paying too much, but am tired of trying to purchase one online. Seems it would be easy, but it's not if my experience is any indication. I'd like to verify that the cue is not a fake and not stolen. Does anyone here know where the serial numbers are on the butt and shaft, and if there is a data base somewhere I can check to verify? Thanks!
