1967-77 K Istanbul 22" Medium Ride cymbal weighing in at 2520 grams. These were the last cymbals that Zildjian made in Turkey. This one has nice stick response and complex tones. Check out the clip. The cymbal is in great shape; no flea bites & the hole is perfectly round. There is tape residue on the back of the cymbal. Someone etched their name & initials in the back.
