Hi all,
I recently bought a 1970s era 22" Zildjian Swish. It has seven rivet holes in it; six are spaced at equal intervals around the circumference (12:00, 2:00, 4:00, 6:00, 8:00, 10:00), with the seventh right between two of them (1:00). It's actually a very logical pattern that offers good flexibility depending on one's preferences; I was wondering, is this a Zildjian factory drill pattern or was a previous owner just clever?
