He sure looks magnificent all right & has the right body shape & aged look about him to possess tusks like that.

Indian/Asian Elephants had tusk weights up to 160lbs in at least one case & a lot from 90lb to 100lb, so not impossible, those look in the 68lb to 78lb range, depends on his body size a fair bit, I have seen a deco or 2 that had some massive looking Bulls in them .

A bull like that would have been some thing to hunt in the jungles a couple of hundred years ago, the Bull Asian Elephant just looks so much stauncher than the African to me.
