This metal Rogue Trader-era Imperial Psycher, Psyker or Astropath (depending on where you look) was one of the first releases for the then-new Warhammer 40K game.
He has “Astropath” on the front and 1987 on the back. I don’t have a sculpting credit for him, unfortunately – I have the list of which sculpts Bob Naismith did of that range and he hasn’t taken credit for him.
