You're killing me with this one Nathan. I know that I found something years ago and never figured it out. Now my brain hurts trying to find this one. What I had found was, apparently after seeing yours, was just 1 half of whatever it is. When I had the single side/half, I thought it was the twist handle from an old doorbell, the kind you twisted and the bell inside rang rapidly. Now, seeing both halves, I think I was way off. I hope someone on here can solve this for you, (and me).
