A note about cracked cymbals: Over time and usage, cymbals can develop cracks for various reasons.
The information really comes from all the people who have contributed to discussions over the years.
We know Avedis Zildjian started production in 1929 in the Quincy, Massachusetts USA. Hard to see in this photo is the "genuine turkish cymbals, made in usa" but it's there, it's a complete logo.
This is a rough guide to help estimate the age of your cymbal. In the thirties Zildjian's most popular cymbal measured between 8 and 14 inch, weight paperthin, easily bendable. In the fourties Bebop drummers began to use larger rides and sizzle cymbals. First Stamp 1920s-1930s Very rare case of a misprint.
For this reason, we do sometimes sell cracked cymbals, and price them accordingly, hoping that you'll milk every last ounce of music possible out of them.
