I happen to have a pair of vintage (60s) Avedis Zildjian 15" hi-hat cymbals as well as a pair of vintage (60s) Paiste Formula 602 13" hi-hat cymbals.
Just wondering whether either pair of these "hats" would have been factory-issued with any vintage kits from this era or whether they would have been considered "special ordered" sets?
As usual, any words of wisdom would be greatly appreciated!
