This is a 21" Zildjian ride cymbal that has been hand-reworked by a local cymbalsmith.
The cymbal was lathed and hand-hammered, including the bell, to thin it down and add some character.
The result is a pleasing take on the old A Zildjian sound, with a cutting bell and controlled ride. It's not dry, but it doesn't build up too much.
It weighs 2591g, which makes it a Medium Heavy.
It's in excellent condition, no cracks or keyhole. Some finger prints.
