Here's the sad thing. I just went to my machine, camera and micrometer in hand, to help you out.
It was only as I was standing in front of my game, wondering why the key wasn't on the hook, that I remembered that my Sorcerer has never had a head lock since I've owned it.
Well, can't say I wasn't trying to help. Just came up a little short on the "succeeding" side of things.
