I am trying to determine what make of layered tip is on my 1999 Troy Downey cue. It is black on the side of the tip (the burnished area) and is kind of a blueish-greyish light blackish color on the chalking area. I called Mueller to ask Troy Downey what he was using in 1999 but I'm sure the tip would have been replaced since then from the previous owner. I bought the cue used online and can't seem to be able to contact the previous owner for clarification. Does anyone have any idea what type of tip this could be. Thanks for any help.
