The first article linked includes some things not often familiar even to Z users, but my recollection from a few years back (ok, a little over a half century back) is that when you bought a new Zildjian it came with a little description of the "family history."

One of the exceedingly rare cases where RTFM was actually interesting!

Now I'm looking (since a couple of decades or so ago) for the even rarer case where RTFM is still useful. (I can remember a few ancient events indicating manufacturers once upon a time weren't too ashamed of their stuff to tell you what it was supposed to do. They don't seem to do that anymore.)
