1970s Zildjian 20" Swish features a "China" style with rivets. Gives a "shimmering" sound. This cymbal has not been cleaned and has a lot of dirt and grime (doesn't affect sound). Has 5 of 6 original rivets. A bit of edge wear. Slight keyholing. Weight: 1691 grams. A very nice "player" grade vintage cymbal.
