[COLOR="DarkRed"]Mmmmm...both of those show signs of being hand-hammered to me.

Even the old A's had some machine hammering back in the day. So the '50's-60's ones are gonna show evidence of both.

I think come the '70's that's when A. Zildjians became completely machined. By the time you get to the hollow-ink logos...there appears to be no more sign of hand-hammering. But I definitely have had some late '60's A's which still had some hand-hammering to 'em.[/COLOR]

I see. I actually don't know correctly the meaning of hand-hammered.

Does operating the machine by hand mean hand-hammered?

or hold the cymbal by hand and hammered by the machine?

sorry if I'm saying something strange.

I often wonder why hammering on old A zildjian is such consistent.

not like old Ks which every cymbal has different hammering patterns.

Especially trans stamp or 30s, they must had really amazing skill. I almost can't believe it was done by hand.

Do you know anywhere I can learn about this thing?

I bought The Cymbal Book.

Machine hammered on the bottom, and hand hammered on top.

I'll answer your other questions a little later.

Thank you!:)

[COLOR="DarkRed"]I believe 'hand-hammered' refers to a cymbalsmith with a hammer in his hand, a cymbal, and an anvil (actually numerous sorta hammers). So it's a manual operation, nothing mechanized.

Now, most if not all cymbals today which are called 'hand hammered' are actually both.
