I picked up another interesting pair of hats today. 13" this time. They look to be 1960's based on the stamp but I'm not 100% sure. Top cymbal weighs 930g and the bottom weighs 1050g. No "zildjian" ink anywhere but on the top surface of the top hat is inked "medium" and on the inside surface of the bottom is inked "medium concert". I haven't seen this "concert" ink before. I'm pretty sure these are indeed hi hats based on where the ink stamps are. I don't know anything about concert cymbals but I assumed they'd be suspended or something?? Any insight much appreciated.
