(Superb Condition & Extremely Rare - The Resonant Sound of Pre-Split Istanbul) Istanbul Symphonic 18" Pair I purchased these nearly 30 years ago during my music university days. These are a rare pair from the good old days of Istanbul, before the company split. They possess the beautiful tone characteristic of that era. I carefully selected these from among many similar pairs and sets, paying close attention to their pairing. I believe they have the sound you'd expect from pre-split Istanbul cymbals. They have been stored in a cymbal case, so they are in beautiful condition. Please feel free to comment if you have any questions. Thank you.
