Stamps.

First one (is that the 16" crash?) is an Intermediate Stamp 1959-1966

The next two (the hats?) look to me like Old Stamps. Maybe Type IVb (1959) from the look.

These IDs are based on looking at the shiny new pages of

The Gretsch Drum Book

by Rob Cook with John Sheridan

which has a very nice section by our own Drumaholic (Bill Hartrick) who is the creator of the timeline. I'm sure he'll correct me if I've got it wrong. He's good that way.

All of you reading: You should buy this book if you want the latest and best info on the K Ziljdian timeline, want to know about Gretsch history, and want to support further research.

The A Zildjian stamp shown (you only picture one so I don't know if it is the 18 or the 20) is a 1960s stamp. Both Avedis cymbals would pass for that era to look at them. At least to me.

The K Zildjians alone are worth what you paid for the whole deal, so you essentially got the rest (drums and A Zildjian cymbals and hardware) for free.
