This really is quite a remarkable cymbal. I have it in hand now.
Included in this cymbal are 15 separate hammering clusters on the back-side as well as an extensively and fairly heavily hammered front side much like an EAK. It has a generously sized bell which appears was pressed in and then extensively hammered.
So based on what I have observed and heard since I got this thing its a:
K. Constantinople Custom Hi-Bell Dark Complex Crash Ride Low.
....or KCCHBDCCRL.
I really don't expect this one to become a regular production model because of what MLVB had to say about these proto-types. And its obvious that they did a lot of extra things on this cymbal that they ordinarily wouldn't do on a regular production run.
