I didn't see one, so I thought I would start a thread for pre-trans stamp A Zildjians. If you're not sure what you've got, there should be a cymbal ID thread for that.
You can also check out these two resources:

Just to be clear, some say that there are two stamps that predate the trans stamp, and some who don't think that to be the case. I'd rather not debate that here. Just pics, sounds, and stories.
Just picked this up from feebay. 18" second stamp. Looks like hell, but sounds incredible. Lots of wobble, mellow, dark, quick decay, dry. 1257 grams as is. Using CAD, I figured it was about 1358 grams before repair.
Looks like someone polished the lathing off the top a long time ago. More recently, someone took a rotary sander to the bottom. Not too much though, thankfully.
Show 'em if you got 'em.
