If I could see some pictures of both the cymbal and the trademark I could help you out much better. Off hand it reminds me of a 1970's A that I had once. Your description fits it to a tee.

Yeah, I have played a few good 1970's rides that sounded VERY similar. Unfortunatley I can't take any pictures ATM because the family camera is broken.. But I do know that the stamp dates it to be around the late 60's..

I honestly think that it sounds almost exactly like a nice old K though. The only difference is it's bell, it is very loud, and big. I can record sound files with audacity if anyone is interested? I was thinking of possibly selling it at first but It has grown on me very much!

In that case, can you describe the attributes that make you sure of the time period? Height of stamp, presence or absence of the 3 dots, the type of lettering in the word Zildjian... that sort of thing. You asked about age, but without some detailed info on the stamp its kind of a guess. Do you or anyone in your family have a cell phone with a decent built in camera? Many of the newer ones not only have high resolution cameras but have macro settings that allow for tight closeups.
