I've got a Durbin with an antler sleeved joint (3/8-10 ff) which is a Bocote (I think) plain jane. It's an older cue and looks nothing like his fancier cues, but it sure does play sweet
PS - it is signed in black (hard to see) around the bottom of the buttsleeve. It was someone's bar beater cue that I had Scot Sherbine refinish. The bumper is a modified screw on, now just pushes in.
