Anyone recognize this Stamp?

I've had this cymbal for years, it's an 18" crash/Sizzle. Very trashy sound, but I use it quite a bit. The stamp looks Zildjian to me, but is it? Just curious.

Looking through this site, I found a Zilco stamp that looks pretty close to the same, and with the possiblity of a O on the right side of the stamp, maybe that's it. The original owner purchased it in the mid to late 60s. I also have a Beverly crash cymbal, I'll pull that out and post a picture of the stamp

Thanks
