There is a Paiste 22" Black Label ride for sale on Guitar Center's used gear site. I have called on the cymbal just out of curiosity. I was told it has slight keyholing but that is it. They are asking $199.99 but may go lower if the keyholing is brought up.

Here is the sku# = 105829984 (type into search window)

Here is the serial# = 003088 (1980 I think)
