Zildjian 21" A Medium Ride Cymbal.  Very good condition.    Weighs 2657 grams (5lbs - 13.72oz).  There's slight key-holing, but it was never an issue because I always mounted it properly whenever I used it (and I barely used it).  The key-holing and stains it has today are exactly what it had when I received it.  I gave it a gentle washing.  I purchased this in November of 2015.  At that time, I thought it was likely from the 60's or 70's.  Turns out it appears older than that based on its stamp.  The bell measures about 5.5 inches in diameter.  I like it a lot, just thinning out my collection.  I have many ride cymbals. 

No stock photos used.  All pictures and video are of the actual cymbal listed.  This listing is only for the Zildjian 21" A Medium Ride cymbal and nothing else.  

The cymbal's stamp appears to be what's called the "small stamp" based on widely available research.   This was actually quite easy to ascertain.   However, interestingly this is not the smallest stamp Zildjian used.  Also, the "small stamp" comes in two versions (SS-A and SS-B).  This cymbal has the SS-B stamp-version (the Zildjian Co portion of the SS-B stamp is wider than the SS-A version).  Cymbals with the small stamps were made in the late 50's (1957-1959).  The stamp measures 1.25 inches high and the famous "three dots" (in the triangular arrangement) aren't in the lower portion of the Arabic letters as on other cymbals of different eras.  I included photos of the 1.25-inch measurement as this was consistently used by experts in identifying/differentiating the different stamps used throughout the years by Zildjian.  

This ride cymbal has no black printed logos.  Research indicates Zildjian didn't start putting the typical black logos on until the 70's.

The video was taken with a Nikon Coolpix P500 camera, and the sound was captured by its onboard stereo microphones.  The camera was about 14" from the cymbal.  I also hit a 15" Sabian AAX crash, and a 17" Sabian AAX crash so you could hear how the ride's crash sound compares to other crashes.

This is being listed with no returns to avoid return policy abuse.  However, if you have a legitimate issue, I'll work with you and eBay to resolve things to your complete satisfaction.  This is also covered by the eBay Money-Back Guarantee should it come in damaged or not as advertised.  The buyer will either be totally satisfied with the cymbal, or I'll see that they get their money back.   The shipping option will change regularly, so if interested, buy when shipping cost is in your favor.

Every part of the cymbal will be protected substantially for shipping.  Because it's big, it'll get extra attention and protection.  When the cymbal leaves my possession, I don't want to worry if it's safe or not. The goal is delivery with no damage.  I'll send photos of the packing job before shipping.  Thanks for looking and have a great day.
