Zildjian K, Avedis and Paiste stamp ID

[Joep]

Sorry, as there are probably 100 people asking this.

I got a few old cymbals for not too much, and one is a Zildjian old K 14", another a 20" Paiste, and a Zildjian Avedis 18" with rivet holes.

From what time (and what type of stamp) is the K? These are some pics:

The Avedis is this. I believe I've seen something like this before and then they were dated 60's if I'm correct?

And the Paiste. Is this an old Giant beat maybe?

Thanks!

The K is late 50's to early 60's.

The A trademark isn't clear enough to identify, but it looks like late 1950's from what I can see.

The Paiste is a Giant Beat.

Seems like a nice score!

Well, yes, it was, until he suddenly dropped the deal because of a better offer.
Man, a deal si a deal, I hate when people do that. I've once had an offer 50 euro above a price I agreed to sell it for. I sold it, because the deal was closed... Yeah, too bad, I could have gotten more, I should have waited. Lesson learnt. Not for this guy...
