Azco
Beginning in 1968, Azco (Avedis Zildjian Company) Ltd. started cymbal production. The cymbals were cast and rolled in the Zildjian facility in Massachussetts, and finished in the Azco plant in Meductic, New Brunswick, Canada.* (More information is needed about Azco cymbal models at this time.)
In addition, "Canadian Ks" were also hammered and lathed there after the K factory was closed in Istanbul. **

Hi-Hats - 13"/14"/15"
