Forgive my ignorance if this is an easy question. Im knowledgeable on vintage drums but lacking in the cymbal department. I just acquired some cymbals. One especially caught my attention. Its a 14", has the typical A Zil. engraved stamp on it. On the inside, it has whats left of a stamp that says "bottom hi hat" then "new beat" right under it. Its located at the half way point from the hole to the edge. The letters are small 1/4 inch to be exact. I assumed it was just an old new beat but the lathing on the outside reminded me of a K I use to have. It doesnt look like a typical new beat. Although the inside does look normal. Its light too. It resembles a top more than a bottom. Its 1105 grams compared to another new beat bottom I have weighing 1370 grams. Im guessing just by the small solid letters on the inside someone could date this for me. Thanks
