I recently scored an 18" A. Zildjian & Cie crash, and I'm curious about when it might have been manufactured. From what I've heard, Zildjian sold these cymbals from the late 1960's thru the early 1980's.
I'm wondering if anyone can tell from these pics (appearance, lathing patterns, stamp) a bit more precisely when within that timeframe it might have been made. It weighs 1323 grams.
Any help or info is much appreciated.
