Help Identifying 2 Zildjian Crashes' DOP

[Viktor ZM]

I came across these 2 Zildjian crashes and they look like they are from the 60s. But since I'm in Brazil and in a "remote" area on top of it, I'm finding highly unlikely that that is the case. If they are indeed from the 60s it would be the firsts from that period I see here since forever, i guess. Much appreciated any help.

Looks like 60s to me with the 3 dots stamp and the deep bell lathing.

I agree, looks like 60’s stamp to me!
