SABIAN Vintage 20" Ride Cymbal

Late 1970's-1980's vintage Sabian ride. No further markings to indicate AA/AAX/HH etc except for the Sabian Cananda stamp. Long and Mcquade evaluated this as an AAX but there's no definitive indication. 20 inch heavy ride with big heavy bell. Medium-bright sound with long sustain. Easy to manipulate bell harmonics on this cymbal. Slight keyhole, been there for years no issues.(see picture). No cracks or any other damage except cosmetic wear for its age. $190 or best offer.
