Not an easy find, I've got one, made from a predator 314 PRE-CAT, I had Ohmen make it for me, I'd sell it but I have 300 into it between the shaft I paid 200 for, and the cost to have Ohmen re-thread it, clean it up, put new Moori tip on it, and match ringwork, so price will be high.
This shaft hits sweet, but I don't play with the cue. Not really wanting to sell, but I would if u need the shaft. PM me
I have 2 OB Classics... One with just the black phenolic joint and 30 inches and the other has matching rings to the southwest (the standard southwest rings) I can do $120 for the 30 inch or $175 for the matching rings one.
