Swapped all my Do-Dad's over to some newer Arlen Ness stuff and this was one of the items that got swapped out. All of the specs are in the link below from the guy who makes them. I've not seen another one around other than this one. There is a tiny little bit of pitting on the edge of the chrome on the backside of it that I never even knew was there until I took it off because it can not be seen at all. Goes for $175 +shipping on his site but I'll sell this one for $100 shipped.
