Looks like a Chandivert Champion tip to me......

It may be a wizzard tip.
The Wizard tip doesn't look like your pictures. Why does it matter, anyway?Hmmm so the general consensus is Wizzard? It is also a Chris Nitti cue, so perhaps that may be a clue if he favors a certain tip.
Chandivert Champions are single layered tips, aren't they?
This one is multi-layered and uneven. I'd go with Talisman or Hercules.
