With the way the center is cast into it I thought it might be Super Bell but Pete and Jakes confirmed their biggest drop is ~4". This looks to be 5" or maybe more?? Any idea who carries these??
Looks like some retrorods carries... http://www.retrospeedandmachine.com/catalog/index.php?main_page=index&cPath=2_91
Interesting thing about their catalog (#43), they describe their dropped arms (AR-2119) and deep drop arms (AR-2121) but never say how much the drop is. WTF? Anyway, it doesn't look like a CE to me.....
