This vintage cymbal is in excellent shape and sounds great. Purchased from Don Bennett’s drum shop in 2010.

There is a lighter area on the cymbal where the stamp is(pictured). A former owner used a cleaner to get a better shot of the stamp before he let it go.  On the underside of the bell is written intermediate stamp, but after some research, I believe it is a "new" stamp

Actual diameter is  21 9/16
