I have one of those in a blued finish, but it has a different manufacturer name on it. Can't remember who. It is pretty nice, though I don't use it a lot.
I take it that in order to remove the mechanism, you just remove the top screw (I like that idea) my old Williams ratchets I must remove the outer ring and let me say that sometimes that is very hard to do.
Don't get me wrong trying to remove the split ring from those wright ratchets with a pick is ****** murder, let alone trying to get them back on again with shaky hands
Would have been interesting to see this available in flex-head. I wish Williams would have provided clear and updated info to their distributors, because even today (it's 2016), the listings still show dual-pawl mechanism, which is very misleading. I should have just bought a used Facom instead.
