This is the Ogre Champion character from the HeroQuest expansion Against the Ogre Horde. The model isn't a scan, but a remodeled version of the Ogre Warrior character found here: https://springer3dscans.wordpress.com/2017/04/19/mage-of-the-mirror/

The weapon has been switched to the axe of the Chaos Warrior and the position of the weaponless hand altered. The original bald head with long hair on the sides has been modified into a hat and the mouth and nose area has been altered. It's close enough.
