I have a 13"(actually a tad over 13") Old Zildjian paper thin splash cymbal that weighs 14.9 ounces which i think is around 420 grams?. This cymbal is so thin you can get a full crash with the tip of your finger and literally bend it right in half. It is the sweetest sounding splash i have ever heard in my life and i wish i had other sizes as well. It has had a tiny 3/16" edge crack for years and has not spread with constant abuse from me wacking it. It is warped a bit from being so thin but still sounds awesome. I am wondering are most cymbals this size in this era around this same paper thin weight and why cant they make them like this anymore?. I tried a new paper thin splash and it sounded like garbage compared to this and felt like hard metal but lightweight. I put on some photos of the cymbal. I did a little research and seems to me this is a Trans stamp from the 1940's? but i had a hard time identifying the different stamps. This stamp has the Z and CO deeply stamped into the cymbal and you can see the stamp from the underside of the cymbal. I bought this and another same weight and size cymbal as a set of hi hats for $10.00 from a music store like 10 years ago and the other one was permanently bent/folded in half like a hat just like i made the cymbal in the photo look like, so i threw it out in the garbage but later someone told me that other cymbal i tossed was made like that? Sorry for the long post but maybe someone knowledgeable can chime in here.
