This is Turnwise, he's a mechanical man. He's the main supporting character in a steampunk style story I'm writing.

Turnwise accompanies the main character (Samuel James Widdershins, or Sam) as he adventures from place to place.

Here we see him holding his tattered remains of a shirt that he'd been wearing for the best part of 2 years.

His right arm (and left foot - not pictured) have been replaced by Sam as they were missing when he first found him and crushed in an accident respectively. The replacement pieces are constructed mostly of brass, iron and copper parts, but his original body is made of some unknown exotic silvery metallurgical mystery.
