Vintage Zildjian trash cymbals 15" Custom

So here is a special effects cymbal , custom built by someone else. 

It came to me from a double bass Zickos kit that was
sold new in Jamestown, North Dakota from Margarites Music. Which is only important if you ever read
FARGO, ROCK CITY by Chuck Klosterman. A great music book!(A heavy metal odyssey in rural North Dakota). Any way . Highly recommended read.
Base is a 15" heavy marching cymbal , with 6 radial vent holes ,includes keyhole. Then we put a felt on top and place the hex Zildjian on top. Looks like a 20"thin cut to 15" hex, includes crack at the bell. Put felt on top and let it flop around loose. Cutting and machining were very well done.
Sound is loud , trashy, with great sustain in a small diameter. This cymbal deserves to live on.

Thanks for looking
