Used Zildjian Avedis Medium Ride 19in - rivets (2008g)

Used Zildjian Avedis Medium Ride 19in - rivets small stamp, late 50's early 60's

edges are a little rough. no cracks or scratches. onset of keyhole. 
looks like it got some homemade modifications such as:
- 6 rivet holes, 1 rivet missing. the other 5 rivets show quite some patina and verdigri. 
- what looks like some very sparse, thin hammering marks. 
brilliant finish shows patina that's consistent with age, which is true for stick marks and finger marks as well.
