I am just wondering what kind of time frame this cymbal was made. I've looked a pic after pic trying to guess before asking here. But I've given up. It's off a 20" ride, pretty light in weight (don't have a scale to weigh it on). Although the pic doesn't show it, the stamp actually distorts the cymbal by almost over a 1/16th of an inch forming a slight mound at the stamp. I would think that the stamp would distort down into the metal, forming more of a pothole. But it forms a mound as if it were pushed up from under the cymbal. It's the single dot in the middle that is throwing me for a loop - I can't seem to find another pic with just the single dot. The stamp seems to be heavier at the ends on the Z and o.

Guesses?
