Gary Hunt miniatures and comes in a pack with 6 in. 3 like the one I have used here, and 3 with scythed wheels. The zed is from Mantic Games and is multipart plastic. Legs, body, head and right arm. Needed to cut the base away from him, and a slight modification to the neck unless I wanted him to stare right up at the sky.
The small red you see on the wheels are my monogram J F. The base need some stones and stuff, too empty right now. And I promised some scale shots. So here you have EM4 Miniature on the left and Studio Miniatures on the right. Hope this helps.
