A Paiste 2002 20” Regular Crash. 
This particular cymbal has been used as a Gong cymbal. It has had 3 small holes drilled into the top of the cymbal. 
Also could once have had rivets in it. 
Very neatly and carefully done to protect the cymbal. 
It still sounds like a normal powerful crash. 
Some light marks on the front. Some lines were tape has been applied on the back but overall a lovely cymbal.
