Also notice that “crash ride” is written upside down.
First Stamp 1920s-1930s This stamp has the prewar arabic script and a very low 'made in usa'.
These were produced at the Avedis Zildjian factory in Norwell, Massachusetts, after the company won the rights to the “K Zildjian” brand.
For a few years, they produced hand-hammered cymbals and thus they are included here.
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.
There is no book, so far, so I took some pictures of my own cymbals over the years and arranged them in a timeline to my best knowledge. Ride size ranged up to 30 inch and 16 inch Hihats are known from this era. In the fifties and later little inkstamps on odd shaped models say SWISH, PANG or FLANGED HI-HATS, MEDIUM RIDE etc. This is also known as the 'pre-ink' period, so before mid 1970s when Zildjian started the silkscreen ink stamps on the bottom with the open ink-stamp logo. This picture was send to me by email from a fellow Zildjian afficionado.
