I have an old pechauer that has one. I seem to recall that Fat Cats from academy were that pin as well. As for major brands, old pechauer and I think early predators, but could be wrong.
My Jacoby Hustler has a 5/16x14 flat-faced joint. My more expensive Jacoby D-11 model has the 5/16x14 piloted joint. Look on the Jacoby website and look at the lesser-costing cues. I bet they have the flat-faced joint. Call them to verify this.
