What “thin stamp” era Zildjian had this underside design/lathe??
It is confirmed a thin stamp cymbal (a small underlined “o” next to “Zildjian Co.”), so it has to be 60s to early/mid 70s…
I just am confounded with this cymbal bottom… Even if it was polished by hand, the patterned small round shapes make me think of a much later made Z Series bottom or maybe even ZBT bottom, but per the thin stamp, neither of those could be the case.
Any help?
