Great find! Scrap metals yard? What the..................Is that "Zilcher" above Mehmet on the stamp? Does it have any ink stamping on it? If it does I can bet that's it's green. This is certainly a "pre-split" Istanbul cymbal. In the late 90's, the three brothers Agop, Mehmet and ?? had a big fight, and formed thier own companies. Istanbul Agop, Istanbul Mehmet and Amedia. I believe that Mehmet died not too long ago.From the stamp, this seems to be an older cymbal, maybe early 80's or older.Cool cymbal.
Agop was the one that passed away back in the 90's and they were not brothers, they were business partners. The split occured because of infighting between the surviving family of Agop's and Mehmet. They couldn't agree on the direction to take the company, so now we have the two Istanbul cymbal companies. Agops are manufactured a little differently than the Mehmets now.....sonically I prefer the Mehmet Istanbuls....they sound better to me for the most part.
The split with the brothers you may be refering to is the Zildjian split between Robert & Armand ZIldjian. The story is all connected actually. Agop, Mehmet, and the third guy that started Amedia all worked for the K Zildjian factory at one time. When the American Zildjian company bought out the K Zildjian company, they moved it to their factory in Canada during the 70's. All K employees were given the option of moving to Canada as well or staying behind with no work. Two of those that stayed behind were Mehmet & Agop, who opened Istanbul cymbals. The ones that went to canada turned out some fine K's. Then the split between Robert & Armand happened. Robert got the formula and the Canadian factory, but not the name Zildjian. Hence the Sabian company was born. Robert also got to keep any of the workforce that decided to stay with him rather than move to Norwell to stay with the parent company. With that Robert got some of the finest sounding hand hammered cymbals from that early HH line that Sabian made. So if Agop and Mehmet had made the move to Canada and then the USA, there would be no Istanbul cymbals of any brand, pre-split, Agop, Mehmet what-so-ever. Kinda glad they decided to stay behind :D
Good score on the pre-split Istanbul BTW... :)
