18" Zildjian K Istanbul from around 60. I think it is a new stamp, but i'm not sure. I can send you some pictures if you are interested.
I am located in Denmark so you are going to pay about 70$ plus the price if you are from the states.
The cymbal has 8 rivet holes and a slight keyhole, but nothing essential. There are also few small cracks around the hole, but they haven't developed in 15 years.
The weight of the cymbal is 1474,17 making it a medium cymbal.
