This ride cymbal is in very good condition with minor cosmetic wear. There are no cracks and the edges are free of dents and dings. There is minor wear on the center hole but there is no keyholing. The stamp is still visible but there are no other markings. We believe this cymbal to be from the 1960's or 1970's but can't 100% confirm that. This cymbal has a weight of 2366g.
