The hollow block printing dates this Sabian Medium Heavy ride to the first couple of years of the Sabian factory, after it parted ways from Zildjian. This is an AA type cymbal, but pre-dates the use of the model designation. It is a Medium Heavy ride (you can just see the printed logo in the second picture) and it weighs approx 2700 grams. No cracks or keyholing. In excellent condition for its age. In Nanaimo
