Vintage Zildjian K Heavy Ride 20” Pretty old! I’m not great at dating cymbals but pretty sure it’s 1980s, maybe 90s. Notmuch wash so wouldn’t use it as a crash ride bit has a great ping to it, would work great in a jazz context Could do with a clean but I was always taught that age gives the cymbal character and to treat them like a cast iron pan! Fire me a message if you have any questions! :)
