Looks like a freshly cut LePro, when the coating is no longer on and it hasn't been sealed or burnished yet. It also looks nearly identical to a current Triumph. A triangle is actually lighter color, nearly white sometimes. All three are water buffalo, and all three are colored according to tanning solution. An Elk Master is blue because of the tanning process. That's not chalk. It's white when it's shaved to size after install. It's water buffalo, too. I bet when you install that Champion, shave it to size and burnish it, it'll be dark brown, too. That's a pretty typical color for Chandivert tips.
Like I said, I won't argue that those old Champion tips weren't made from cow calf, because I don't know for certain. I do know enough to have credible doubt, so I won't bite off on cow hide unless there's some documentation to say otherwise. It would be nice to know, just for curiosity sake.
Drawing upon an old memory here....Elks and Blue Diamond....chromium tanned
LePro et al...vegetable tanned
...whatever that means
