Hi I've been trying to figure out this cue for a few months even taken it to a guy very respected in our community for his knowledge on cues and still no answers.almost everyone who trys it thinks its something special and most people say bushka or helmstetter but I just want to make sure its not a cheap knockoff. It has a 5/16 18 thread I believe and was told the ferrule was ivory due to it being a dull yellow when I got it.
